Forgive me if this is a duplicate post, but I don't use jigs with (keeper) collars and instead attach a grub grip I found works no matter the lure size or jig used.
Like all of you I got tired of tearing up my solft plastic lures whether on jigs or skirted jig trailers and came up with this idea 10 years ago. It's basically a wire clip that holds plastics in place and allows them to be used over and over even after catching 20 fish.
First off, for you ball head jig users, no collar is always better. The collar may hold the lure for a while but splits the soft plastic at the same time. Soon the lure slides down the hook after a number of fish are caught.
