Hi, David, I have the care of a 7' Korean made piano with a Renner action. I have taken no measurements yet but the kass keys have no lead weights at all. There are some weights in the treble end. The touch is so-so, uneven and on the light side which pleases the jazz players at this evpensive seafood restraunt. Weighing out this action is not really an option but I would like your opinion as to the most effecient way of handling this situation. How much lead is desirable to remain in a 'normal' inertial range? How would 'low' inertia be percieved by a musician? Considering the work these springs and strings are doing what would your forcast be regarding long term longivity? This piano is used by name brand players, like Kenny Barron, and the person in charge of maintenance is concerned about quality. The owner is concerned about cost, hence this piano instead of a superior Japanese or American make. I look forward to your replay and seeing you later this month. Newton nhunt@rci.rutgers.edu
