I would guess the suckers are under bobbers. If you are hearing about trolling large suckers it might be Muskie guys. Whatever you troll, Spoons, Cranks, Bucktails pump the rod occasionally. When the bait pauses thats when they will hit.
thanks i will remember to try that. like all rookies we usally only tried trolling when we couldnt cast them, basically confirming they werent shallow.
we would just put on crankbaits and try to find the weed edge. which is alot harder than it sounds LOL
