Trevor Burgess –
Used this worm for a weekend trip on the lake and caught several bass. The salt release made fish bite consistently, even in low visibility. Works great with a drop shot rig.
Neil Knox –
Felt more natural than other plastic worms I’ve tried. The thickness helps it stay in place and fish seem to be more interested. Good for both finesse and shakey head setups.
