In our lake we have more white crappie than black and we always catch a lot more whites than blacks. More so when pulling cranks than when fishing jigs, we catch more blacks spider rigging but not more than whites just a higher % than when pulling. I think I read somewhere that blacks were more of an insect eater while whites were more of a minnow eater, but I don't know that for sure. So yes in MHO the blacks are less likely to hit a CB.
