Suspending jerkbaits, lipless crankbaits, tight wiggling/flat bodied crankbaits, drop shot rigs w/ finesse type plastics like a robo worm, or a gulp minnow, and or a jig. Thats what I usually have tied on in 40 degree water. I know other guys that like big spinnerbaits for slow rolling, jigging spoons, silver buddy, and they do well with those too.
