Not sure about fishing up there but when we fish lakes like Potholes, Scooteney, and Moses we just troll cranks around rocky areas. Then around sandy areas we'll run walleye spinner harnesses, mostly using firetiger for the blade. We've also switched out the regular hooks or made our own then use the Mustad Slow Death hooks for the worm harness to give the worm a good spin. I know some people use blade baits too to jig for walleye.
