Yea, I use them all the time. With different bodies I can get different rates of fall and I've always had good luck with them. I actually started using them when fishing smallies in a river when I was a kid and they did the trick when nothing else would. My supply has dwindled since I moved out here and I just happened to notice I am out, completely out, which is what spawned my thread. I'll be ordering up some here soon it looks like.
