Gosh dangit man you want all my secrets! Ok, just between us. I have property on a great private lake in central Indiana. For crappie there the bait of choice is a red head tube jig with a white tail retrieved real slow under a cork.
Intersting thing is last time I fished there for crappie I caught a couple really nice CC (3 to 5 pounds) on the same rig! I was amazed they hit that tiny bait.
Right or wrong, I have the best luck with crappie keeping the bait just above them. That is why I use 1/8 oz at Olin when trolling. Anything heavier drops me into the fish or below and they don't seem to be interested.
