Re: What role does length play?
I really can't add much to what BigCliff has said. He's right on.
I too favor an 8', 8'6" or sometimes even a 9' rod when fishing small creeks in tight cover. I'm simply rolling, dipping and dapping... no need for a back cast. Now... I'm even eyeing a custom built 10' 2wt... be fun to try.
