Deps "SILICON STOPPER" is the direct fix for reducing worm displacement. It’s a small rigging accessory made to keep soft plastics from sliding down the hook shank and to hold bait position correctly on jig heads and offset hooks.
If the issue is not bait slippage but fish wanting more action, switch to a different soft-plastic profile or a bait with built-in movement. If you need a more natural, compact presentation, keep the worm but add a stopper like Deps "SILICON STOPPER".
