Here is a interesting idea I found looking for some fly patterns. Got the link to the site from FAOL.

Fly Tying the Anglers Art

Look at the "Bug Eyed Jig" in episode #403. I definitley see an application for crappie, maybe using something different than the poly yarn. The chenille head would give it a softer head than the traditional leadhead. I'm not sure about whip finishing chenille, would think you would need to use ultra size. I am gonna get me some of those 60 deg. bend hooks and barbells and give it a shot.
