Gandolf,
I may be wrong, but
I believe the first Grey Ghost was tied specifically for Crappie fishing . It's certainly effective enough on Crappies.
I've tied lots of little feather wing streamers for 'gills. Usually downsized versions of classic style bass streamers, primarilly because I like to tie them, they are pretty, and fun to fish. They worked quite well.
I don't know about the whole 'movement' thing, though. My 'gills don't seem too particular about it, and crappie mostly like anything that looks like a minnow.
