I agree, I think most musky pulled at the view are just by luck. But if I were going to target them in the winter and I have thought about this a lot. I would fish a good size swim bait with a chunk of perch meat on it. A good location would be just under the ice and right where a lot of people are fishing for perch. A lot of people try to put them back down after they've brought them up from the deep and they end up floating back up and get stuck right against the bottom of the ice. I would be pretty sure some musky are cruising looking for an easy meal.
