But definatly on the strong side. The hammers are just a bit light, but not so much that the keys start slowing down on return. (they are heavily front leaded) To attempt to answer your "worms" question. I like pushing the borders, and then comeing back at a piano to back off a bit where I need to (as in blubbering hammers resulting from tight checking and letoff/drop settings.) > > As for the Yamaha, the only thing I can think of is just what others have > been suggesting, action frame bedding.
