Hi John Have used Appox. 20 sets of Tokiwa red backed pre-cut sets from Pacific Piano for a year or more now . I have found them to be very consistent and reliable ,and they do a nice job that dampers are supposed to do . I think there a bargain roughly 60 ish dollars a set . If non backed felt is desired I believe American/ schaff carries the french felt which Is also nice . With either felt our shops s.o.p. is to slit the tri-chords just a little more and add a peice of kite string as it never fails that the tri felt are not perfectly split or that the agraffe spacing is'nt quite perfect. The kite string and extra split effects a bettter overall shutoff and we do not usually have to go back later and trouble shoot it as we're trying to get the piano out the door and delivered by 5 p.m. or whatever. Best Dale Erwin
