I was at the fly fishing show this past weekend and watched a youngman named Olli from Eumer tying tube flies. He was tying mostly salmon flies so I asked him for a demonstration of some smaller dry flies and nymphs. He obliged me and tied some on micro tubes and brass. I was impressed and decided since I have the setup for tube flies for my NorVise to go ahead and buy some micro tubes and brass. I was wondering how many of you tie tube flies and in particular smaller tube flies for trout fishing?
