Has anyone used these? Saw these have an o-ring molded into the worm. I have no idea how this would hold up once a fish hits it.

Cool idea. I can't imagine their durability is great, but I would try them.

They are going to get sued for that. There is a small lure company called "Vinner Baits" , they have been making a lure called the "wacky stick" with the insert or o-ring for a few years and I believe he has a patent so if you like these from big bite baits you better buy them quick as I know a cease and desist letter has already been sent.

Hard to imagine much of a law suit there. I just tried to find their website and appears to be offline or no longer hosted.
