I would focus on the 1/32 to 1/16 sizes, try blade baits. I was there in May to fish redear and gills and actually caught more crappie up to 16 inches using Boolie jigs which is a jig with a small propeller behind the head. We had a few 50+ days fishing those baits while I was there. Beautiful black crappie, fish like those are few and far between here in Missouri.
