Since there were so many threads that I could not read all of them (sorry), but I've been wondering why the tapering the punching felt does improve the tone. I may be wrong but I wonder if it reduces the noise when the key hits the felt. Think of the hammer shape. It produces nice tone when it has a round egg shape. If this is true for the punching felt, how about a conical shaped punching? NY Steinway uses conical shaped punchings for the balance rail, so I just thought it could be possible to make the same kind for the front. What do you think? (Sorry if it was already discussed.)
