If your TPE, stretchy soft plastic or traditional plastisol keeps sliding down your jighead, the problem may not be the bait. It may be the way the jighead is trying to hold it.
Quick Answer
Most soft-plastic retention systems concentrate retention near the nose of the bait, immediately behind the jighead.
That works extremely well for some applications.
But we wanted more from the design.
On The Upgrade Multi-Purpose Jighead, we deliberately moved the lead bait keeper farther down the hook shank toward the belly and thicker portion of the soft plastic.
We did that for three reasons:
| # | What moving the keeper accomplishes |
|---|---|
| 1 | Create space behind the jighead for bucktail, living rubber and other materials to be tied onto the hook while still retaining a soft plastic behind them. |
| 2 | Move some additional weight toward the belly of the bait to influence balance, fall and retrieve. |
| 3 | Create holding power farther into the thicker body of the soft plastic instead of relying entirely on the nose. |
That makes the keeper more than a retention device.
It’s part of the entire jighead design.
And that’s the bigger lesson: when choosing a jighead for TPE or plastisol, don’t look only at whether it has a bait keeper. Look at where the keeper is, what shape it is, what material it was designed around and what else that keeper allows the jighead to do.
Why Do Soft Plastics Slide Down a Jighead?
There are several possible reasons.
Your soft plastic may slide because the keeper isn’t compatible with the bait material, the keeper is too large, the bait is highly elastic, the nose has become damaged, the bait is rigged crooked, the hook doesn’t match the bait, repeated casting has loosened the plastic, or the keeper only grabs a small portion of the bait near the nose.
TPE makes some of these problems more obvious because it behaves very differently from traditional plastisol.
Highly elastic material tends to stretch.
Traditional plastisol tends to puncture, tear and conform more easily.
That means a keeper designed primarily around plastisol may not behave the same way when you push a stretchy TPE bait onto it.
TPE and Plastisol Are Different Materials
This sounds obvious.
But the fishing industry has spent a very long time treating soft-plastic retention as though every soft plastic behaves basically the same.
They don’t.
Traditional plastisol can be soft, firm, salted, scented, thin, thick or flexible.
TPE and other highly elastic materials can offer extreme stretch, tremendous durability, tear resistance, different buoyancy, different density and different movement.
And those material differences matter when you’re trying to attach the bait to a piece of metal and lead.
A keeper doesn’t just need to hold the bait.
It needs to let you rig it correctly in the first place.
Why Traditional Nose Retention Works—And Where It Has Limitations
Let’s make something clear.
Traditional nose-style bait keepers aren’t bad.
They’ve caught an unbelievable number of fish.
Molded lead collars, barbs, wire keepers, spring locks and screw locks all have applications where they work extremely well.
The question we asked wasn’t “How do we prove everything else is wrong?”
It was “What else could a bait keeper do?”
That’s where the design process changed.
Most conventional retention systems concentrate their holding mechanism immediately behind the head of the jig.
That creates retention at the nose.
But it also occupies valuable space.
And that location limits what else you can do with the hook shank directly behind the head.
We Moved the Lead Keeper Down the Hook Shank on Purpose
On The Upgrade Multi-Purpose Jighead, the lead keeper doesn’t sit directly against the back of the jighead.
We moved it farther down the shank toward the belly of the bait.
That wasn’t cosmetic.
It wasn’t different just for the sake of being different.
We wanted that one design change to accomplish three separate jobs.
Reason #1: Make Room for Bucktail, Living Rubber and Other Materials
This was a major part of the idea.
Traditional nose-retention systems occupy the area immediately behind the jighead.
That’s also exactly where you’d normally want to tie bucktail, living rubber, feathers, flash, synthetic fibers or other dressing materials.
Put a large lead collar or bulky retention system there and you’ve taken away much of your tying space.
Move the keeper farther down the hook shank?
Now you’ve created a different opportunity.
You can tie material near the jighead and still have a dedicated soft-plastic keeper farther back.
That means the same jighead can potentially be a conventional soft-plastic jighead, a bucktail, a living-rubber jig, a hybrid hair-and-plastic presentation, a feather-and-plastic presentation, or something an angler creates at his own bench that we haven’t even thought of yet.
That’s why we call it Multi-Purpose.
Why Does Tying Space Matter?
Because customization is part of fishing.
There are anglers who don’t want to buy a finished lure.
They want to build one.
They want white bucktail with a paddletail trailer. Living rubber with a shrimp body. Flash with a TPE minnow. Feathers with a traditional plastisol trailer.
Whatever.
The point isn’t telling anglers exactly what they’re supposed to build.
The point is giving them room to build it.
A bulky nose-retention system can make that difficult.
By moving the keeper farther back, the area directly behind the head remains available.
The keeper doesn’t have to own that entire piece of real estate.
Reason #2: Move Some Weight Toward the Belly of the Bait
The second reason is less obvious.
Lead isn’t weightless.
If you’re going to put lead on the hook shank for bait retention anyway, where you put that lead matters.
Moving the keeper farther down the shank moves some mass farther away from the nose and toward the belly of the bait.
That can influence balance, orientation, fall, roll and retrieve.
Instead of putting every bit of lead as far forward as possible, we’re distributing some of that weight farther back.
The goal is a flatter, more balanced presentation than concentrating everything entirely at the nose.
It’s not the same concept as our Hover Hook, where belly weighting is much more pronounced.
But the principle is related: weight placement matters.
Jighead Weight Isn’t Just About Ounces
Anglers spend enormous amounts of time debating 1/8 or 1/4? 1/4 or 3/8?
That’s important.
But two jigheads of the same total weight don’t necessarily behave identically.
Where that weight sits matters too.
Move weight forward and you change the balance.
Move some farther back and you change it again.
That’s why we think about total weight + weight placement.
Not just the number stamped on the package.
The bait doesn’t know it weighs 1/4 ounce.
It responds to where the mass is and what that mass makes the entire rig do.
Reason #3: Hold the Bait Farther Into Its Body
This is probably the most obvious retention advantage.
Look at most soft plastics.
Where are they usually thickest?
Not necessarily at the very tip of the nose.
The middle or belly portion of many paddletails, minnows, shrimp and swimbaits contains considerably more material.
So why rely exclusively on retention at the nose?
By moving our keeper farther down the hook shank, we’re trying to engage the soft plastic farther into the body where there’s more material available to hold onto.
That’s particularly interesting with highly elastic TPE.
Instead of asking the first small section of the bait to do all the work, the keeper engages farther into the bait.
More material around the keeper can mean more useful holding power.
Why Nose Retention Can Eventually Fail
Every cast creates force.
The jighead accelerates. The soft plastic follows.
Then you twitch it, snap it, bounce it, hit grass, hit structure, catch fish.
All of those forces act on the connection between the bait and jighead.
If all retention is concentrated around a damaged or stretched nose, eventually that area can become the weak point.
This is especially obvious after multiple fish.
The bait itself may still be perfectly usable.
But the nose has become torn or stretched.
Now it slides.
Moving retention farther into the body gives us another way to approach that problem.
Why TPE Makes Keeper Design Even More Important
TPE doesn’t necessarily fail like soft plastisol.
Instead of simply tearing, highly elastic material can stretch, bunch, distort, pull around the keeper or resist seating.
That’s why throwing a larger and larger chunk of lead at the problem isn’t necessarily the answer.
Sometimes a giant keeper actually makes TPE harder to rig.
You push. The bait stretches. You push harder. It bunches. You finally get it over the keeper.
Now it’s crooked.
That’s not much of an improvement.
Why Taper Matters
A bait keeper shouldn’t simply be judged by how big it is.
Shape matters.
A tapered keeper gives the soft plastic a more gradual transition onto the retention area.
That’s especially important with highly elastic material.
Instead of immediately encountering a large abrupt obstruction, the material progressively moves onto the keeper.
That can make rigging easier, straighter and more repeatable while still providing retention.
This idea becomes especially important in our A.T.V. products.
More on that in a minute.
What About Screw-Lock and Spring-Lock Keepers?
Spring locks and screw locks are proven systems.
With many traditional plastisol baits, they’re fantastic.
But look at what they occupy.
They’re still generally positioned at the nose of the bait.
And they use the same area immediately behind the head where you might otherwise want room for bucktail, living rubber, feathers, flash or other tied materials.
They also require the bait material to interact with a screw or spring.
Traditional plastisol often does that extremely well.
Highly elastic TPE can sometimes stretch, twist, resist threading or bunch around the spring.
Again: different tool, different material.
What About Wire Keepers?
Wire keepers are another excellent solution for many applications.
They’re generally less bulky than traditional molded lead collars and can provide excellent retention with plastisol.
But they still solve primarily one problem: hold the soft plastic.
Our question with The Upgrade was broader.
Could the keeper hold the soft plastic, leave room for tied materials, move some weight toward the belly and engage the thicker portion of the bait?
That’s a different design objective.
What About Traditional Molded Lead Collars?
Traditional lead collars work.
No question.
But they’re usually concentrated directly behind the jighead.
With plastisol, that can provide excellent retention.
With highly elastic TPE, a large abrupt collar can sometimes become difficult to push the bait over.
And once that lead occupies the area immediately behind the head, it also reduces the available tying area.
Again, that’s not necessarily a flaw.
It’s simply a limitation of that particular design.
Is The Upgrade the Only Jighead That Does This?
There are countless jigheads, custom pours and niche designs on the market, so we’re careful about claiming nobody has ever done anything similar.
But our design philosophy is unusual because the keeper location is intentionally being used to solve multiple problems at once.
We’re not just trying to keep a soft plastic from sliding.
We’re deliberately using the keeper location to provide soft-plastic retention + open tying space + additional belly-positioned mass + deeper body engagement.
That’s what makes the Multi-Purpose design different.
The goal isn’t simply “our keeper is better.”
It’s “our keeper does more.”
Why We Call It the Multi-Purpose Jighead
This is really the heart of the product.
The Upgrade Multi-Purpose Jighead wasn’t designed around one soft plastic or one technique.
The open space behind the head means an angler can customize it.
The tapered belly-positioned keeper means it can retain a wide range of soft plastics.
The exposed hook makes it useful for conventional swimming and jigging presentations.
And the weight distribution becomes part of the bait’s overall balance.
One jighead can become a paddletail. Shrimp. Minnow. Bucktail. Living rubber. Hair-and-plastic hybrid.
That’s what we mean by Multi-Purpose.
The A.T.V. Series Was a Completely Different Design Problem
Our A.T.V. Weedless family presented a tougher challenge.
We wanted an EWG-style weedless hook.
That immediately changes what you’re working with.
The soft plastic has to sit correctly on the hook, remain weedless, maintain enough hook gap, move naturally and release properly when a fish bites.
There simply isn’t the same freedom to move a lead keeper halfway down the hook shank.
That area is needed for the bait and EWG geometry.
So we had to solve retention differently.
What Could We Actually Improve on an EWG-Style Keeper?
The category already works.
That’s important to acknowledge.
EWG and weedless weighted hooks have been around for a long time because they’re effective.
We weren’t interested in pretending the entire category needed reinventing.
The real question was: where is there still room for improvement?
For us, the answer was the nose-retention system.
A lot of traditional weighted weedless hooks use relatively bulky nose keepers.
They work with certain baits extremely well.
But that larger, abrupt geometry can limit compatibility with different soft-plastic materials.
So we focused on the shape.
Why the A.T.V. Uses a Tapered Nose-Retention System
Unlike the Multi-Purpose Jighead, the A.T.V. can’t use the same belly-positioned lead keeper.
It’s a different tool.
So we designed the nose-retention system to be tapered rather than relying on a large abrupt chunk of material.
Why?
Because we’re trying to accommodate a broader range of TPE, elastic plastics, traditional plastisol, bait thicknesses and bait profiles.
A highly elastic bait shouldn’t have to stretch around an unnecessarily bulky obstruction if we can achieve useful retention with a more gradual shape.
Again: bigger isn’t automatically better.
Why Some Bulky Nose Keepers Become a One-Trick Pony
A large nose keeper may hold one particular type of soft plastic extremely well.
That’s great if that’s all you fish.
But change the material and things can get complicated.
A keeper designed around a conventional plastisol swimbait may become frustrating with highly elastic TPE.
A keeper designed around one bait thickness may be oversized for another.
That’s where we think taper can create more versatility.
Instead of designing around one ideal soft plastic, we’re trying to accommodate more types of baits.
That’s the Upgrade philosophy.
Not one perfect bait. Not one perfect technique.
More useful options from the same piece of terminal tackle.
The Multi-Purpose and A.T.V. Keepers Solve Different Problems
This distinction matters.
Upgrade Multi-Purpose Jighead
The keeper is moved farther down the shank to leave room behind the head for bucktail, living rubber and other tied materials; move some mass toward the belly for a flatter, more balanced fall and retrieve; and engage the thicker middle portion of the soft plastic for additional retention.
Upgrade A.T.V. Weedless Family
The EWG geometry doesn’t allow the same belly keeper.
So instead we focused on a tapered nose-retention system designed to accommodate a wider range of soft-plastic materials and profiles without an unnecessarily bulky obstruction.
Same philosophy. Different engineering solution.
Does The Upgrade Work With Traditional Plastisol?
Yes.
That was essential.
We don’t want anglers to need one box of terminal tackle for TPE and another for plastisol.
But we’re also honest about the compromise.
Very soft, delicate plastisol can sometimes tear or blow out on an aggressive keeper.
That’s possible.
No retention system is perfect for every material.
A keeper gentle enough for the softest plastisol imaginable may not hold stretchy TPE the way we want.
A keeper aggressive enough for elastic plastics can sometimes be more than an extremely delicate bait needs.
Design is compromise.
The goal is finding the useful middle.
Can You Use TPE on The Upgrade?
Yes.
Compatibility with highly elastic plastics was one of the major considerations behind the keeper design.
The tapered shape helps avoid the giant abrupt obstruction found on some conventional retention systems.
And on the Multi-Purpose Jighead, moving the keeper farther down the shank allows it to engage farther into the bait.
But rigging still matters.
How Do You Rig a TPE Bait Correctly?
Before putting the hook through the bait:
- Hold the jighead beside the soft plastic.
- Identify where the hook should exit.
- Insert the hook directly into the center of the nose.
- Follow the centerline of the bait.
- Exit at your predetermined point.
- Carefully work the bait onto the keeper.
- Make sure the bait is completely straight.
Then look down the bait.
If it’s crooked? Fix it.
A crooked paddletail can roll, spin, track sideways, reduce tail action or twist line.
The best keeper in the world can’t fix a bait you stabbed sideways.
Don’t Use a Bigger Hook to Fix a Keeper Problem
This mistake deserves its own section.
If the soft plastic keeps sliding, anglers sometimes move to a larger hook.
That’s not necessarily solving anything.
The keeper holds the bait. The hook catches the fish.
A bigger hook can restrict bait movement, fill the body with unnecessary metal, change balance or interfere with tail action.
Choose hook size based on bait thickness, body profile, hook gap and presentation.
Then let the retention system do its job.
What About Glue?
Glue can work in some situations.
But we don’t think adhesive should automatically be the first answer to a poor bait-and-keeper combination.
First ask: why won’t the bait stay on?
If the keeper isn’t compatible with the soft plastic, glue may simply mask the problem.
Different TPE and plastisol formulations can also react differently to adhesives.
If you use glue, make sure the adhesive is compatible with the bait material.
But we’d rather start with mechanical retention that actually works.
Why Does My TPE Bait Keep Bunching?
Usually because the material is stretching around something instead of moving onto it cleanly.
That might be an oversized lead collar, a large barb, an incompatible screw lock or another abrupt keeper shape.
Slow down.
Don’t simply push harder.
TPE isn’t plastisol.
If the material keeps stretching instead of seating, consider a different keeper design.
Fishing shouldn’t require a hydraulic press.
Why Does My TPE Paddletail Keep Spinning?
Retention may not be the only issue.
The bait could be rigged crooked, mismatched to the hook, distorted by the keeper, paired with an inappropriate weight or naturally rolling harder than expected.
Remember that jighead weight changes action too.
We’ve seen the same soft plastic behave considerably differently on a 1/8-ounce head versus a 1/2-ounce head.
Sometimes additional weight creates harder roll and more aggressive movement.
That’s useful when it’s intentional.
It’s a problem when it’s not.
Jighead Weight and Weight Placement Are Different Variables
This is one of the biggest ideas behind The Upgrade family.
Anglers usually think: how much weight?
We also think: where is the weight?
A conventional jighead concentrates most of its mass toward the nose.
Our Multi-Purpose keeper moves some additional lead farther down the hook shank.
Our Hover Hook takes that concept much farther by intentionally positioning the weight toward the belly.
Different weight placement can affect orientation, fall, roll, retrieve and horizontal posture.
Ounces tell you how much weight exists.
They don’t tell you where it is.
What About the Upgrade Hover Hook?
The Upgrade Hover Hook takes belly weighting much farther than the Multi-Purpose design.
Available in 1/16 oz, 3/32 oz and 1/8 oz, all on a 3/0 2X hook.
It’s designed for presentations where we want the weight farther into the bait rather than concentrated at the nose.
That can create flatter orientation, more horizontal presentation, slower finesse approaches and different fall characteristics.
Again: weight placement is part of lure design.
What About the A.T.V. Weedless Hover Hook?
The Upgrade A.T.V. Weedless Hover Hook combines weedless EWG-style rigging, 3/32-ounce weight, 2/0 or 4/0 hook options and a lighter, more horizontal presentation.
This lets anglers match hook size to different bait profiles while maintaining the same weight.
It’s another example of why hook size and jighead weight should not automatically be tied together.
They’re separate variables.
Does Scent Work on TPE?
Yes.
This misconception needs to disappear.
Compatible fishing scents can be used with TPE and traditional plastisol.
Scent can be applied to elastic paddletails, shrimp, minnows and finesse baits just like traditional soft plastics.
But externally applied scent doesn’t last forever.
Water continuously washes it away.
After several casts, reapply. After a fish, reapply. After dragging the bait through cover, reapply.
If scent is important to your presentation, treat it like something that needs maintenance.
TPE doesn’t prevent scent from working.
And plastisol doesn’t magically make externally applied scent last all day.
TPE Has a Major Durability Advantage Around Toothy Fish
This is one of the places highly elastic plastics can really shine.
Species such as speckled trout, bluefish, Spanish mackerel, snook and flounder can absolutely destroy soft plastics.
A soft plastisol bait may lose a tail after one aggressive strike.
TPE can often survive substantially more abuse.
That means fewer replacement baits, less rerigging, more casts and more time with the lure in the water.
During a hot bite, that’s a real advantage.
But only if the bait actually stays on the hook.
Durability and retention have to work together.
What About Z-Man ElaZtech?
ElaZtech is one of the most recognizable highly elastic soft-plastic materials in fishing.
Its stretch and durability are major reasons anglers use it.
Those same properties are also why pushing it onto a conventional keeper can sometimes become frustrating.
If an ElaZtech bait bunches, slides, won’t seat correctly or rigs crooked, don’t automatically assume the bait is the problem.
Look at the keeper.
A different retention design may make the bait considerably easier to rig and fish.

Is TPE Better Than Plastisol?
No.
And plastisol isn’t automatically better than TPE.
They’re different materials with different strengths.
TPE Can Offer:
Exceptional durability, extreme stretch, unique buoyancy, resistance to tooth damage and potentially longer bait life.
Plastisol Can Offer:
Incredible softness, huge variety, different scent formulations, different densities and excellent action.
Use both.
We’re not interested in convincing anglers to stop fishing a bait that’s getting eaten.
The fish gets the final vote.
Frequently Asked Questions
Why does my TPE soft plastic keep sliding down the jighead?
The keeper may not be compatible with highly elastic material, the bait may be rigged incorrectly, or the retention area may have become stretched or damaged.
What bait keeper works best for TPE?
Look for a keeper that provides useful retention without requiring highly elastic material to stretch over an unnecessarily large obstruction. Tapered designs can make elastic plastics easier to rig.
Why did The Upgrade move the bait keeper farther down the hook?
The Multi-Purpose Jighead’s keeper was moved farther down the hook shank for three reasons: to leave room for bucktail, living rubber and other tied materials behind the jighead; to move some additional mass toward the belly of the bait; and to create retention farther into the thicker portion of the soft plastic.
Can I tie bucktail on The Upgrade Jighead?
Yes. Leaving open hook shank directly behind the head was an intentional part of the Multi-Purpose design so anglers can add bucktail, living rubber, feathers, flash and other materials while still using the dedicated soft-plastic keeper farther back.
Why doesn’t the A.T.V. use the same belly keeper?
The EWG-style weedless geometry requires the soft plastic to occupy that portion of the hook. Instead, the A.T.V. uses a tapered nose-retention approach designed to accommodate a broader range of soft plastics.
Are spring-lock keepers bad for TPE?
Not necessarily. Some combinations work well. But highly elastic material can stretch, twist or resist threading onto certain spring- and screw-lock systems.
Can I use plastisol on The Upgrade?
Yes. The keeper system was designed to bridge TPE/elastic and traditional plastics, although extremely soft or delicate plastisol can sometimes tear on a more aggressive keeper.
Can I use glue to keep TPE on a jighead?
Some adhesives may work, but compatibility varies. Start by making sure the bait and keeper are mechanically compatible.
Does scent work on TPE?
Yes. Compatible fishing scents can be used on TPE as well as plastisol. Externally applied scent should be reapplied regularly as it disperses in the water.
Why does my TPE paddletail spin?
It may be rigged crooked, distorted by the keeper, mismatched to the hook or reacting to the jighead’s weight and weight placement.
Is TPE more durable than plastisol?
Highly elastic TPE-style baits can often withstand substantially more stretching and tooth damage than very soft traditional plastisol, although individual bait formulations vary.
The Bottom Line
A bait keeper looks like a tiny feature.
We think about it as part of the entire lure.
That’s why we didn’t simply ask “How do we make the plastic stay on?”
We asked: what else can that piece of lead accomplish?
On the Upgrade Multi-Purpose Jighead, moving the keeper farther down the hook shank lets us do three things: leave room behind the head for bucktail, living rubber, feathers, flash and other tied materials; move some additional mass toward the belly to influence balance, fall and retrieve; and create retention farther into the thicker body of the soft plastic instead of relying entirely on the nose.
That’s why we moved it.
The A.T.V. series presented a different problem.
EWG geometry doesn’t give us the same freedom.
So instead of forcing the Multi-Purpose solution onto a completely different hook, we focused on what we could actually improve: the nose-retention geometry.
Make it tapered. Reduce unnecessary bulk. Create compatibility with more types of soft plastics.
Same philosophy. Different solution.
That’s what we mean when we call something The Upgrade.
Not different for the sake of different.
Not a giant list of features printed on a package.
Take something anglers already use and ask whether one design change can make it do more.
Because the keeper should hold the bait. The hook should catch the fish. The weight should create the presentation.
And if we can leave enough room for you to tie a bucktail, add living rubber, slide on a TPE paddletail and build something we never even considered? Even better.
A keeper that holds the bait and leaves you room to build. Shop The Upgrade family →
