As is often said regarding fly patterns, very little is original nowadays. This pattern is very similar to most scud-type flies being tied today, with perhaps the major difference being the use of Krystal Flash for the ribbing, as well as custom blended dubbing to match the colors of the natural scuds in my home-water spring creek. One of the challenges when tying flies that are fished sub-surface is that of getting the color of the dry dubbing blend correct so that when it gets wet the color change that occurs fits the true bug being imitated.
