I see you are playing around with different Ideas and materials .
fly number 1 is a modified woolly bugger .
not sure if you done this or not . but wrap the hackle in the opposite direction as you wrap d the body material .
fly number 2 is a marabou winged streamer . interesting chose of body materiel
would make a nice nymph pattern with out the wing ,I generally use tinsel or floss for a body
cray fish pattern is that a zonker strip tied in for the back ?
