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.
The infamous No-Hackle Dun as written about by Swisher and Richards, originally called the Double-wing Sidewinder, and made famous by Mike Lawson. I can’t tie them worth a dang.:
Funny the Rat Faced McDougall gets ya… The Goddard Caddis is one of my absolute favorite flies both to use and to tie… Small spun hair bodies on dries should be easy as there is so little there…
When trimming them I shove all of the hair up by shoving the body down between my thumb and forefinger and I make three cuts… One flat along the top and then knock the two corners off. All three cuts turn down when approaching the tail.
Then I turn it upside down and repeat. Very little trimming is needed after that. The body tends to be slightly wider than tall which I think is both an advantage for floating and looks better.
I am struggling with getting the huge articulated flies we use here to swim better…
For me, just about anything with quill wings including the original S&R no hackle mentioned above but also all of those classic quill winged wet flies.
Just now the one I wish I could avoid tying is the Daddy Long Legs with pheasant tail legs. Not because it is difficult, but I need several hundred double knotted pheasant tail fibers (6 per fly) for the several dozen I have on order.
It goes with any fly when I have to tie up more than about 4 dozen at once.
I had to force myself to learn how to tie it since it was not available in any Fly Shops in CA. That pattern killed on the Roaring Fork and Frying Pan. These days, if I need a tying challenge, all I have to do is open this book…
