I can't see that it makes any difference. The top and bottom are so 
nearly equivalent in compression levels, there's nothing you can do 
about it either way. These are differences much smaller than those 
realized from one piece of wood to the next. and well below the inherent 
"noise" in the system.

My take, anyway.
