The first time i used them, I caught fish good. I use the white ones more out of superstition than anything. I've just always been that way even though I caught fish my while life before they came out. I think having confidence in what you are using is a big part of catching fish. It's not that I think they help that much, i just am too superstitious to put them down! Ha. They are funky though. I'd like to know what they are made of too.
