Joe,

I agree that the Wurzen felt the Crescendo punchings are made of could 
be ideal for key end felt.  It is firm, yet resilient enough to avoid a 
slapping noise when the key end meets the damper underlever.  I am in 
negotiations with Wurzen to see if I can get it.  I have been told they 
can make me whatever I want, as far as thickness, density, and 
resilience, etc. goes.  The problem lies in knowing exactly what we as 
piano technicians need (and conveying it to the factory in terms they 
understand, which I am trying to learn) and a sticky little issue known 
as the minimum order size.  But stay tuned, I am optimistic I will have 
some good news to report soon...
