They are kinda squared-off. They do not check well and they are attacking the new backchecks. The piano owner is not interested in a new action, but rather to just try and make this one work reasonably well.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Thanks for any suggestions.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Terry Farrell</FONT></DIV></FONT></BLOCKQUOTE></BODY></HTML>
