I'd be casting a 1/16oz marabou Roadrunner, myself. May even go up to a 1/8oz one, if I had to get farther out and the pond was relatively deep. And, yes ... you will catch Bass on most anything you fish for Crappie with, live or artificial. People have even been known to catch large Crappie on various Bass lures (as you are well aware of) ... so, there's really no one special bait or method that will catch ONLY Crappie, and no Bass.
