I think that it is the pure wool that they use for all the deep patterns. The flies that I am thinking about are all the big bass type flies that were originally tied using clipped deer hair heads so they would float, like Nix sunfish pattern. There are wool headed versions of most of those flies, I am just unsure of what type of wool that they use and where I can get a hold of it for cheap. I don't see it at the fly shops that I go to and would prefer to get it in bulk somewhere else because I tie and lose a lot of those flies. Thanks
