If you look at convential musky baits, the size of them will amaze you. The idea of a big bucktail spinner is to make as much commotion and flash under the water as possible. Getting a fly to do this is difficult at best. Casting these monsters is even worst. You have to push as much water as you can and also, I like a lot of flash. Give that musky a reason to come and move to your fly. Pushing water is a great way to cause the disturbance that will most likely trigger a strike. I know that most of you are fly anglers but if you are serious about chasing musky, look and even cast a conventional musky rod to get a feel for what is going on under the water. I think you will be amazed by what these baits can do.
