combination with NY Hammers.  The 17mm knuckle distance on the Hamburg
shanks is ideal for the weight of the NY hammers as currently
manufactured. >>

Greetings, 
   I may be reading this wrong, but how can one knuckle distance work for all 
Steinways?  Using geometry to compensate for weight is fine, but there are 
some distances involved that must be considered irrespective of hammer 
weight, such as room for key travel, space for the jacks when the hammer is 
held at check, etc.  
  17 mm knuckle distance is fine until used in conjuction with high ratio 
keys, then you end up with either very little blow distance or deeeeeeeeep 
key dip.  Am I missing something?
