I've been fly fishing for about 8 years now. Last year I went to the contributaries of Lake Erie, steelhead and salmon fishing. I used a spinning outfit but fished with flies. I have a 4wt St. Croix pro graphit for fishing around my home. Was wondering what length and weight I would need to go with to go after the steelhead and not be to overboard to go after small mouth and trout about 20 inches.
