I swing, have for three decades. It appeals to my logic that the heavier
hammers get tighter pinning, since the friction accounts for less of the
total resistance and the mass is more controlled by tighter pinning.
Most of my jobs are pianos that I have lived with for the entire time
and I haven't found any problems with the pinning. This includes industrial
use in practice rooms as well as concert stages and extremely light home
playing.
Rather than "constant" friction, I think it is more important that
there be a consistancy, which can be had by pinning to the same friction or by
graduating it by swinging.
