The UW for a given DW is a function of friction, right? A higher SW 
will increase friction throughout the lever train as its extra weight 
is applied to the bearing points. Extra Front Weight hasn't been 
known to increase friction in the key and it certainly wouldn't 
increase it further up in the action. Hmm.. Which of these actions 
has the higher Strike Balance Ratio? If it's the one with the higher 
SW, that will increase the friction already created by the SWs.

And better response?....Hmm. Would you define that as a higher UW. 
Not every pianist would be comfortable equating high UW with 
responsiveness. Or would you define it as FW, which is the best 
practical expression of inertia. I'd go with that, and the piano with 
the lower FW would respond more quickly to the pianist's attack.

Yea, let's toss some oranges in with those apples and see if anyone 
notices that the applesauce tastes different.
