Aren't you transferring the weight up front anyway?  Just as was 
mentioned the other day with lateral transfer, how much is transferred 
is just a factor of the CG and deceleration rate.  Or is it that 
regardless of the transfer, you don't want to get that much suspension 
movement?

Got it.  So analogous to lateral roll, it's A Bad Thing primarily 
because it upsets the suspension or takes it out of the favorable part 
of its operating range, not because of any inherent physics reason, 
right?
