Thanks, Kurt.  However, I wasn't looking for increase in tower
capability.  I was looking to unload some of the side stress of the
short coupling to the rotor.  It would be nice to be able to transfer
bending moment to a couple of thrust bearings, instead of one thrust
bearing and the rotor housing.
