What is the best go-to bait for muskies following a cold front?

If I had to pick one, (and that would be really tough), it would be some type of soft plastic bait, like a Red October Tube or possibly a jig with a plastic trailer. These lures can be worked a little slower and still have great action that triggers bites. Second choice would be a quality deep diving crankbait, working the base of rock points.
