    Keith ,While I appreciate your supportive words I would submit this 
opinion to be somewhat subjective regarding tonal improvements due to the  
bridge & soundboards laminated structural stiffness and not one I'm trying to 
convince any one else of.
  But back to the Mason A bridge I said in my original post I stated the 
tenor bridge it sweeps but actually it's more of a rightish angle protruding 
toward the bass. 
  After reading others input it sounds as if it would have  made more sense 
to let the long bridge protrude further down for support and mass/impedance 
needs. Is this the concensus? 
  I'd go measure the exact distance the strings were for- shortened but the 
piano is up on its side. It's getting a new board so this bridge modification 
would be no problem to incorporate. Other suggestions of interest?
