The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.
but I have that problem with all CDC flies.
I haven't found an application where CDC is used that I can't adequately cover with snowshoe or a variety of different synthetics
The best cdc by far comes from wild ducks. Of course, you can't buy it, you have to shoot it... ;)
I never use desiccant on this material as it tends to get caught in the fiberious feather and ruins it by degrading the natural oils over time. Best approach is to slap the fly on the water with multiple short false casts (away from the water you're fishing), followed by blotting and a few brisk lung blasts. This method is far superior at ridding fish slime than just swishing the fly. You are good to go for several fish. Eventually the fly will get too soaked for this to work. When that happens, change flies and let the used one dry on a patch. By the time you are fighting a losing battle with drying the second fly the first fly is ready to go again. Besides, you should retie your fly after several good fish anyway, so no time is lost.
