In S. Florida I have had 5 sets that we = installed pulled apart. Obviously the problems were in the low tenor and = bass and not the top 1/3 of the piano, which I'm assuming is why you = stop where you do. I too have found that the reduction in touch weight = far outweighs any concerns for separation in that portion of the = instrument. But as a safe-guard for me, wires throughout the rest of the = piano are mandatory.
