jasper,i made my own rigs,bought some clevis's,crimps and beads.went and got some 4"or 6" round alluminum insulalation covering and cut my own 4" and 5"large cow bells and added some tape to themi, i then punched a hole on one end added a clevis and attached like 3 or4 with some beads on both sides of bell to wire or mono leader.i then added a glow peanut to the say 3" leader. troll them slow,1.5to 1.9.troll them near the bottom so as to hit bottom every once in awhile you should have someone working the riggersup and down.
i would like to use them on round valley but the bottom isn't as level as lake ontario and would be afraid to get hung up.you can also buy the same rigs for $15 to $20 bucks a peice.
