I guess I use heavier than most, but they seem to work for me. I use B&M Pro Staff trolling rods because I prefer to move faster (power troll jigs or push crankbaits.) To me, it's primarily a search method. Once I find a concentration I prefer to move to hand held vertical jigging. If I don't find a concentration they still seem to do well in the pre and post spawn when the fish are scattered. It's really not a favorite way for me to fish because I find it much easier to deal with a couple of 10 or 11 foot rods than six 12 or 14 footers. It works though.
