I was trolling a hump this morning, and a VERY nice fish hit a Monster Shad. In a matter of seconds , he was gone, probably just clamped down on the bait, and opened his mouth. I made a turn onto the other side of the hump, and got a 32" Musky. I then trolled over the original spot, and got a 28" Juvenile Musky, that had large gaping wounds, see pic. There is no doubt in mind, that a LARGE Musky caused these wounds. If you ever are reluctant to run BIG baits, this should boost your spirits.
