Most Difficult Fly
I am sure that I am not alone in this. There always seems to be one fly pattern that is more difficult for an individual than any other. I have seen tiers steer away from a number of different patterns.
For me, the Rat Faced McDougall is one that I really wish had never been dreamed up. I think it was Darbee who came up with this concoction and, for me, it has been my nemesis ever since first tying one. You often hear that it is easy, if you use a razor blade, or if you do this, but it has always been a pattern I have avoided.
What is the one pattern you avoid tying?
