Hi Roger, I agree 4 gms is generally optimum for tone production. But it isn't altogether a matter of friction. You can get 4 gms with spongy cloth. It's the firmness that counts. I'm willing to concede it's possible to have the correct firmness with lower friction - maybe with thicker, heavier emralon saturating the cloth, the current Steinway centers have that additional firmness with lower friction. I don't have a bunch of new Steinways to form any opinion based on practical experience. OTOH, I _do_ like 4 gms for action responsiveness - control, and especially consistent checking (pianissimo) and repetition regulation.
