Even with the load off center, there's nothing that would 
"roll" the bridge. A rectangular block of wood sitting on the 
floor with a HUGE load 1/4 of the way in from one edge will 
sit there quite nicely for the rest of your life without 
flipping over. Bridge roll is, of course, soundboard failure, 
and there's no reason I can think of that off center unisons 
would contribute to soundboard failure. A look at the 
spreadsheet with the resulting lengths, however will most 
likely show little reason not to center them - thus avoiding 
the whole thing.

Some folks freeze it, presumably to prove there really *was* a 
wedding. <G>
