I am trying Hareline's Baitfish Emulator Flash this year. Found it late last year, but it makes a nice sparse Clouser with flash in it, and its super easy to use. It comes on a long strand with fibers about 3-4" long so you can just cut off a chunk for the top and a chunk for the bottom. Pics are of hot pink/fuschia (front) and fuschia/chartruse clousers. The pearl baitfish is another great color. The way its strung you can also wrap it around the hook shank if you want your fly to be more full bodied.
Pikerman....????? I just think bucktail ties in too bulky and tends to spin like deerhair. I was told its poor material I bought and I believe that's correct but I still dislike bucktail. I'm gonna try some of the other materials you mentioned.
