For every problem there is a solution if you only bother think to find a solution or ask for a solution to the problem.
Use a toothpick
Rig your worm, insert a toothpick into the bait, in through the hook eye all the way to the other side and clip away the excess wood, the bait won 't slide.
In my case mother nature has been generous and has supplied us southern fishermen with all kinds of thorny plants so we actually don 't have to worry much about not carrying toothpicks, they are there, all you need is to harvest a few . I prefer huizache thorns over toothpicks.
;D
wow thats a very good idea! im usually pretty innovative but i dont think i would have thought about that. still seems like too much of hassle though, when i can use ewg's with yum dingers instead of yamamotos.
