Have you considered replacing one of the offending unisons to see if
changing the string will solve the problem?  Are you sure the tuning pin
isn't flexing -- or even twisting?  If soda pop got down in the pinblock,
you could have sticky pins!  Or even "glued" pins.

A great idea -- that'll probably find its way to one of the .COM
providers where it will have a limited audience.  I still think a
newsgroup alt.piano.technician is the way to go.  That way it'll be
obvious that this will be pretty much all technical discussion -- with a
few wisecracks thrown in.
