Was just reading about these flies, and wondered if anyone ties them in a smaller size, like for BWO's? Or is their effectiveness solely for imitating those large caddis? jSeems like there are other bugs that would look realistiic hanging down rather than floating horizontally. And those folks like the Spiderweb, but there are other small, strong threads now, is there any reason to use a white thread like the spiderweb? Seems like if you used black or brown for the body, you wouldn't have to change threads.
