Matt,
I grew up catching crappie... Personally, I think they are the best tasting fish, so I really wanted them in the pond. I read the forum for a year before stocking, and conventional wisdom said to stay away.
But, I have to learn some things the hard way, and if I don't mind keeping a lot of skinny, hungry bass, then I should have a decent shot at keeping the crappie under control. Time will tell.
I'm hoping mine will be big enough to begin harvesting some next year. If they keep up the current growth rate, they will be some good eating next year.
Hope your plans work out. I'll probably start a bluegill rule like yours next year, after they have had some time to really establish.
Good luck with your plans. GaryTexas
