I did not recently tie these flies. They are part of a batch tied several years ago. I have always thought this Rosborough fly pattern to be his best creation. I have rarely deviated from the gray body, although you so easily could. I have used different body materials besides the called for Muskrat fur (and guard hairs). This is a good example of a ‘classic’ pattern (at least in the Western U.S.) that has evolved away from natural furs to synthetic components. The tail and dubbed/strung collar  are the guard hairs from a patch of Muskrat fur. Today, I would opt for the simpler brown hackle barbs of a hen feather for the tail and the collar. The body has been tied with the underfur dubbing of the Muskrat…even today one nice dubbing material. But, again, synthetics are available too..and, I have even used cat (Kudra the Cat) fur with good results, although it does not seem to have the density for larger flies. The very appealing Ostrich Herl at the thorax is a favorite of mine for a wound body (abdomen-gills or thorax-legs) as well as extended tails (The Orb). Research Polly Rosborough or better yet buy his simple little book Fuzzy Nymphs. Don’t discount the information as too simplistic or too old because of the older techniques shown. This Central Oregon legend was a bug stalker. He set the tone for the more sophisticated Rick Hafele and Dave Hughes. (The Complete Book of Western Hatches).
