John, I cannot answer your question and this may be a hijack of your thread and I will apologize up front, but, several times you have posted that you have been using the BVK 5wt and using 4wt line on it. Is there a reason for underlining the rod? I am just curious and nothing more.....Maybe I can learn something here.....
Just asking and nothing more....

Fly fishing and fly tying are two things that I do, and when I am doing them, they are the only 2 things I think about. They clear my mind.
