Jude, I think it's great thatyou will be testing this experimentally. One factor you might want to look at is how the lead holes in the keystick affect its flexibility. It seems to me that a keystick with several large led holes close to the balance pin would flex more on a hard blow than one with fewer or smaller holes further away from the balance pin. Looking forward to hearing and discussing y our results. \ Mike > [Original Message] > From: Absolute Piano <absolutepiano at comcast.net> > To: Pianotech List <pianotech at ptg.org> > Date: 7/12/2006 9:02:37 PM > Subject: Re: Inertia, was "Grand Touch" > > Thanks Vladan and all for all the info. > > There is a lot to chew on.
