Crappies on the fly

I sometimes use a streamer made from craft fur.  Usually white.  Works great at times.

Clousers work great.  Cheech's low fat minnow is pretty good too.  A simple bead in front of some marabou or craft fur is deadly at times too.  I usually just fish them with spinning gear though, under a bobber with a twitch or two & slow retrieve.  My control is much better with spinning gear, to get into brush piles and other structure.  If you are able to catch in open water, or great with placement, then wouldn't be an issue.  I'd personally go through 5 leaders in a day of crappie fishing with the fly rod (I'm usually decorating the brush piles with spinning gear too).  I have used a fly rod as a cane pole before, to vertically drop into structure pockets.
