The problem with teflon is that it has no plastic memory, once deformed it stay deformed. _That_ is the problem S&S had with the stuff. I would be much more concerned about the soundboard and other wooden structures shrinking and cracking. If the piano is moved to a dry climate I would find a way to reduce the humidity gradually over a period of two to three months to prevent hygroscopic shock and wood cracks. The action will change but not as much as other structures. On the other piano I would seriously look at over weight hammers, spread action and capstan location, in that order. Also check that the knuckle location and size are proper for the piano. Lot os luck. Newton
