I'm just picking a number. 80%. Now... if 80% of the time a crappie feeds up in the water column then why does a lure have a bottom AND top color scheme. If the back is hidden by the belly it could be that the back does not even to be painted with the same results. (I know the lures with front and back colors present 2 different colors at once)

I was waiting for my wife to have x-rays today and this popped into my challenged brain.
