[CAUT] Seiler Flexing

[Andrew Anderson]

Perhaps this is yet another argument against trucks where they can be  
avoided.

When the concert grand is positioned the stage hands know to properly  
position the casters so as not to torque the keybed and thereby adjust  
the regulation parameters.  With trucks, you had better regulate to  
what is there.
