I don't think there is one rod that can do it all. The size of the stream, wind, and are the bushes tall, small on the ground. I have a 2wt and 4wt. One is 7ft other is 7'6". I am going to get a 6foot. Also depends on the size fly I am going to be using. I do fish fiberglass rods and I think with them you can go a line or two, up or down and the rod still will cast well. With graphite is believe it is harder.
