I'm not sure if anyone has herd of them but the helgamite is my third bait of choice. I usually catch them in the Neosho River under rocks below the KG&E dam. One weekend last spring, I cant remember how many lines we set (over 20) but we were using helgamites and leperd frogs on all of them. We checked and reset them 3 times and had caught 43 cats(Caught mostly on the Helgamites). If you have them in your area I strongly recomend using them.
