Has Anyone used one much?  what are your thoughts?  what conditions would you use it in?  seems to be a little different then a wart. 

I've fished one a lot and have yet to catch a fish on one. It's really nothing like a wart like I thought it was supposed to be. 

^^ I agree. I bought one of each color when they came out. Fished them once or twice in the spring for a few casts, and switched to something else. I'm sure they would catch fish if I threw them more often, but I just have too much confidence in my Warts and DT's. 

Caught a couple smallies with em. Good for rocks but not brush. They do not go over limbs well. They are fragile so if you crank rocks you may get a day or two out of em. They have a lot of resistance for a moderate diver.

I prefer the lil johns.

I agree good crank but no evasive hunting action like a Pre-Rap Wart.
