Bio spawn worms

Anybody used them? I bought a coue packs and they look good. Curious if anybody has had any success with them.

I've used them but not the "pro" worms. I tried em on a wacky rig but I was slightly disappointed they didn't have the action I thought they would. The "pro" version of them are supposed to have more action.

Their Vile Craws are outstanding though, full bodied and have amazing action. I recommend them.
