I have learned what little I know about tying trout flies out of books and videos. Unfortunately, I have never been in a position where I could discuss what a better tyer was doing or ask questions. I learned to dub flies by taking a little dubbing, usually too much, and twisting it around the thread into a string which was wrapped around the hook. I learned to use a dubbing loop to make buggy or fuzzy looking flies, mostly nymphs. But watching LeRoy Hyatt on the WKSU series I learned to make a tight dubbing loop and dub dry flies in that manner. It seems to a better method for me in some or most situations. What do you guys do? Do you know any little tricks to make better looking flies (especially to the fish) or easier to do methods?
