Ken,
Did you find the increased dip to be a problem?

because
the longer key provides additional wood that introduces more inertia. This was
proven rather dramatically to me with a "D" here at Oberlin that was built in
1987, had post 1984 shanks (17mm action center to knuckle distance), good
upweight/downweight specs, and was always perceived as being heavy. At this
moment, I can't find my notes on that piano that would tell me what the key
ratio average was; but, suffice to say, that it was significantly below 2
to 1.

light,
so much so that I wished I had not moved the capstans so much. Nothing else
was
changed other than the capstan and wippen heel position (the latter gives the
wippen more mechanical advantage also) and now people were saying the piano
was
a little on the light side.
