"The latest fly I tied for YouTube is the Light Cahill, a classic pattern that I've been tying and fishing for over 25 years. This fly is tied Catskill-style, and carries a lot of tradition with it. I especially like to fish this pattern in faster runs and pocket water, as it floats superbly due to the hackle.
The Light Cahill features the Allen Fly Fishing D101BL dry fly hook, which I am using on many of my dry flies." - Tim
