Heavy action

I have a Baldwin SF-10 here on which I just measured the action
weight.  C4 is 60 grams down, 45 grams up!  Friction -- obviously is
good -- down weight bad.  I hate adding lots of lead to the keys, but
on this piano there are only 3 weights in the bass section, 2 at C4,
only 1 in the upper treble, and actually 2 in the _back_ of C8.  It
appears that they did straight pattern leading on this one.  I can
add 1 - 2 weights to each key and bring it down to 44 at A0, 42 at C4
and 40 at B7 (I'd probably just take out a back weight on C8).  

There is a point of diminishing returns on some actions where you can
reduce downweight by adding leads but the additional inertia makes it
feel to the player as though it is as heavy as it was before.  Does
anyone think I'd get into inertia problems adding this amount of
lead?
