I prefer a rather strong repetition spring. Not so strong that you "feel" to
much of it when playing. 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.)
