This is one of the best all-around nymph patterns out there. I use them frequently and they catch fish now just as good as they have for the last many decades. I modify mine a bit from the original pattern now. Tungsten bead, 10 wraps of .025 lead wire, curved Klinkhammer hook, pheasant tail tail instead of golden pheasant, and brown or black nymph skin instead of the turkey quill back that always gets cut in two after a few trout chew on it.
