The BRF Sparkle Dun has been my steady dry fly for many years. I have caught more fish on this fly than any other, well except for a certain beadhead contraption that I stole from lastchance! Tied the Sparkle Dun in many versions and settled right back to BRF's Original and Improved versions with only one exception. I over dress the deerhair wing on half of my ties for use in heavy water. Never had a problem with "seeing the wing". Never had any problems with floatation using silica powder, and I treat the entire fly. Craig Mathews created one of the best ties ever. Long live the Sparkle Dun.
