I have never caught a muskie on a fly rod and only caught them on "regular gear" when I wasnt fishing for them. But muskie is a VERY aggresive fish. When hooked they will fight themselves to death quicker than any other fish I have ever caught. I actually used to raise tiger muskie when I was able to buy the babies, but I cant find them anymore.When they got to big for me I would just give them to local aquariums. They really are a beautiful fish, but will eat anything in their path. I have caught them on live goldfish, minnows. chunks of blue gill. Steel leader wouldnt be a bad idea. but a real heavy braided spiderwire will usually do the trick.
