the rings are famous for coming off. Personally, I try to glue all mine on. With the rings on, they will somewhat match the dive curves listed on website or precision trolling book. without them, you're kinda on your own. an alternate is to use the walker divers which are same diameter but no rings. I use 20lb trilene xt for walleye leaders. for steelies, I switch to 30lb trilene xt or "big game" mono with snubbers.
