You should try a palmered hackle body as Haul suggested. You can clip the hackles flat on the bottom if you want it to ride in the film.
I always stack and cull the shorter hairs and fibers before using elk hair for the wing. As far as flaring goes the advantage of elk hair is it does not flair as much as deer hair - making for a more natural representation of the tent wing of a grannom.
Looking at your flies I would suggest you use more hair and fewer wraps around it. Try and cinch down the elk hair with 4 or 5 wraps, lift the butt end of the hair and tie off on the hook shank.
