I cought a three pounder last friday on one!!
My dad bought a handful of them last year and he swears by them. The only thing is they break off where the tail sections pivot. I have about five or six with broke off tails. Mostly because of Jacks, (Chain Pickeral for you yankees

)
But they do work! Slow study retrieve and you better be paying attention!
We also have the side hook version. It has a single hook on one side with a weedless wire. Thats the one I cought the three pounder on. I was trying for a wounded fish, with a twitch or two into a fast then slow retreive and then stop for a pause to let sink almost down about foot. Then repeat the pattern. I was going over the hydrill grass crap in a big pond.
Try a couple they work.
