I have been chucking flies for a good many years and have always had a problem with the tippet section of my leader becoming severely twisted when casting traditional or "Catskill" style dry flies. The fly spins like a propeller during the cast, but WHY?
My tippet length is 30 to 36 inches and sized proportionatley to the size of the fly.
