I've used it in trout streams across Minnesota, Wisconsin, Iowa and also in Montana. I like to use this on a double nymph setup behind a heavy point fly or split shot. The body of the fly is determined by the thread color you choose. Olive and brown/olive are good thread colors. Wire can be a variety of colors as well. I like copper because I normally fish bog tannin stained trout streams of the Upper Midwest. Very effective fall/winter pattern in the Driftless areas of MN, IA and WI.
