  Hi Vince
  I think it has more to do with the pressed felt over the woven=
 felt. On the other hand it reasonable to think that springiness=
 in felt is, well... springiness. I'm not clear about that I only=
 know what I heard & felt on my D. 
   I think Ric's comment about  the key stick  acting more like a=
 catapult where the front end comes down on something solid and=
 stays put even though the back of the key still may be in a=
 slight state of flux,does makes some rational sense of what I=
 think I'm perceiving. I can't wait for more experience with=
 this.
   If you have a piano that's familiar to you & you know it's=
 sound well & all you do is change the punchings & there's a=
 tonal change then this is the perfect A-B comparison to be=
 relied upon as proof. It's a repeatable experiment.
  Regards
  Dale Erwin

  I wonder if pre-compressing the punching's would give similar=
 results ... pre-compressing by stringing the punching's on a=
 slender threaded rod, then with washers between the punching's=
 and wing nuts, squeeze the whole thing together by tightening=
 the nuts, and storing them that way until needed.
