Yup, that's the general set-up I use for muskies... when the bite is tough, I pull out my beetle spin swim bait, or "B.S." lure as it is informally known in the muskie camp. The tougher the bite is, the smaller the blades I use because they spin faster giving a more frantic sound (IMO) and the larger bait portion, appearing to swim slowly after its prey, becomes a key target to inactive fish.
With the size you got there Wacker, I'm betting that should be a smallmouth catching machine!
