I don't think the fish care about the clipped wing. I measure my wing and then the pull back the fibers to make the body and clip the center out of the remaining material. If anything gets clipped off it is the tails if they are way too long. I usually tie them on an undersized hook so a two feather dun on an 18 hook would be on a ten or twelve hook ordinarily. I also use hackle sized to the fly body rather than the hook. That doesn't leave any bare hook shank below the body and makes lighter fly.
