If you have a copy of Pop Fleyes then you'll know what a rabbit candy is. It's an epoxy fly using super hair and a zonker strip.....if the crappie are that shallow, then there's no need for a deep rabbit candy. Just a rabbit candy.
Check out the warmwater archive of patterns. There's a yellow rabbit candy that I put in there sometime last year. It will give you an idea of what I'm talking about. The zonker tail shimmies just like a soft plastic jig.
