I fly fish. Mostly for trout, a little for bass, and I have tried pike/musky. Are you completely new to fly fishing or just looking for advice for doing it for musky on the chip? If you are totally new to fly fishing, don't learn to cast with musky flies. They are really wind resistant and tough to cast. Learn the basics with something easy, then step it up. I have caught pike but not musky with flies on the chip. What has worked best for me are baitfish imitating streamers with long synthetic fibers or deer hair , like enrico pugalisi flies, lefty's decievers, or clouser minnows.
