I use Beaver on 90 percent of my dry flies and have for many years. I believe it is much beter than the newer dubbings they have come out with. It is shorter in fiber length and will come of the thread if you get to much on. Can't do that with synthetics. It will also do very small flies very easy. I bleach and dye it the colors I need and have a life time supply of it. Good Stuff for sure. Ron
