These are my "go to" dry flies when fishing for native trout across Western North America. Most of my favorite flies are actually attractors as I tend to find that the isolated nature of most native trout populations means that the fish are not overly picky. This is not to say that there aren't times when these fish do get picky and for those situations it is a good idea to have a few match the hatch patterns at your disposal.
