I find it pays to have a variety of styles. In addition to above, I like parachute caddis, and use it most. My wings can be elk hock, coastal deer, mink tail guard hairs, woodchuck guard hair, or dry fly hackle bunches. Posts are variable length and typically polypropylene, sometimes Antron. Parachute hackle is usually dark dun irrespective of body color, and undersized compared with a mayfly parachute. I also tie extra hackle versions for dry dropper. I generally find sparse downwings preferable on pressured waters. Though dead drift is more typical, parachutes skittered is an option though not designed for it.
