Hi Joe, This isn't exactly what you were talking about but the winging style on these emergers works really well. The deer hair is set in a dubbing loop spun and wound then split. They land superbly and float really well. You can use this technique for dun imitations as well. It isn't restricted to deer hair either, CdC and snowshoe hare also work really well. It does correct the problem of orientation of the wing you mentioned.

Cheers,
A.
