Lots of neat stuff and possibilities. The tail feather fibers are a standard in the "Pheasant Tail Nymph." I like the fancy marked feathers on the back for decorative salmon flies and classic style feather wing streamers. If hardened with some epoxy, they make nice stonefly wing cases. I've never tried using the small, green head feathers as soft hackles for tiny wet flies or midge pupa, but they might work well. Female pheasant skins (or grouse) are better for soft hackle applications IMO.
