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.
