Just two cents worth on this. I had a buddy (now deceased) who was a master of renegade fishing . The old boy almost exclusivly used that fly with devastating effect. The cool part? He fished #8's. He always fished them dry. We thought he was nuts. 'Cept for one thing .He got fish , and very consistently.
He's gone and I sure wish I had his knack with that (oh my gawd they look huge when held up near a #14) fly.
