Don't remember who posted this or where I first saw it; but, it changed the way I tie my buggers now. I add about six strands of "Flashabou" (Rainbow) and tie it into the tail and leave some extra strands hanging while completing the body and hackle. Then, I take a couple of twists to the "Flashabou" and wind it up through the body and pass it in between the hackle wraps to just behind the hook eye and tie off. When wet looks to me like a flashy minnow or something similar. Anyhoo - it accounted for my biggest trout ever about two years ago. A 28" brown between 11 and 12 pounds. Cut him loose to live another day. Tie 'em all that way now.
