Hi Ric,

Back to the problem on hand...

- Since the balance weight and friction seem fine, I
will assume that the action doesn't feel heavy when
you play a slow, quiet piece.  Is that correct?  Can
you confirm?

- Since the BW is in spec, helper springs are not part
of the design, unless someone modified the action and
added lead.  Any evidence?

- I mentioned this before, but will ask again: if
there is marginal clearance between the back check and
the hammer tail, there could be some contact on the
way up when you play really fast or loud.  This
happens because of the flex in action parts when you
apply force.  You will not notice the problem when you
move the hammer slowly.

- Could the action centers be too tight?  I am sure
you would have noticed that.

- Take a few sample hammers off and measaure the
strike weight.  Here is the reason I say that:  with
the nice 5.5 ratio, good BW, and no excessive lead, it
would seem that the strike weight must be fine, but
some (European) manufacturers hide addittional lead
under the key tops.  This is lead they know for sure
will be needed, so it goes in automatically during
production.  The rest is visible and amounts to
adjustment lead.
