Hagens has light wide ones, Lakeland has HEAVY narrower ones. I have both and use them for certain situations, one being heavy deep fast water along shore on the out going tide. I do not however even care about them so called rattling or whatever they are supposed to do. I have completely stopped trying to make them vibrate or rattle and I catch more fish on them now. My favorite way is to use 2 beads now, bottom bead just big enough to keep the bell body from slipping completely over it and the top bead a size or 2 smaller. If I need more weight I add a small brass body or bead inside the bell.
