Ed McMorrow's (author of "the Educated=20 > Piano") pianos are a perfect example.

We still have the fact that most pianists like to feel a clear=20 'response' caused by for instance the combined weight of keys, dampers,=20= action parts, the moment of let off and drop. Whether the instruments=20 plays light or heavy depends on the wish of the pianist and the skill=20 and experience of the technician. Applying too much anti-friction material causes an action not only to=20 feel light and speedy, but also slippery and uncontrollable. In regard to all this I like Horace's remark : "All of which is to say that these issues are matters of perception;=20 and, subsequently, matters of communication".
