How much lead is in the keys?

Hello List,
I am now looking after a 12 year old Petrof concert grand which has been
aquired by a church for recital use etc.  It is a super piano tonally and in
great condition, but it looks as though I will have to attend to the touch
in the near future.  I have played it extensively myself and had a top rate
professional pianist try it out and the basic problem appears to be that it
becomes tiring to play because the touch 'appears' heavy.  On measuring the
touch weight weight however, it comes out at an average of 48g (easy)
downwight and 28g up. Present regulation is very good.  It is Renner action
with smallish Renner hammers which I am sure are original. The action ratio
is in the 5.5 range.  It has to be said that I intend  taking the action
apart and check out all the centering and any key friction, and I expect
this to make the touch more even.  That said,  I still appear to have a
fundamental problem which I will need to be addressed, and I am asking for
comments and ideas on how to approach this.
Don't hold back!
