Dear Avery,

   The Yamaha felt punchings for grands are nearly twice as firm
as the Kluge style. They do make a softer dark green style punching
for their uprights. The grand style has a clearly defined inner
weave with outside layers of normal felt.  Easily observed when
comparing them to the Kluge felt is the very small amount of flex
that happerns on the edges of the felt due to the tight inner weave.
The Kluge style, after intial vertical compression, tends to bluge
outwardly a great deal due to the inner weave differences.

   Who actually makes the punchings for Kluge? I only refer to them
as that since they are standard equipment with Steinway keyboards.
We also have a Hambury D. It gets tortured daily and I suspect
we will change the Yamaha punchings on an annual basis.
