Yes, mass does make a difference. Check the archives, I've written on this in
the past. As have others.

RicB's comment about 'adding mass'  to the bridge pin by pushing (for instance)
a screwdriver blade against, it or on top of it, suggests that maybe
thicker/longer/heavier bridge pins may work better in the top regions.  Even the
lightest pressure on my Bechstein 'B' top treble bridge pins eliminates the
false beating.  Translating this into permanancy is the next question.  I
currently tune a Stuart piano where this type of falseness is unknown.  OK, the
construction of these instruments is very different, but there is certainly a
considerable amount of 'mass' in the bridge aggraffes through which the strings
pass.  Is this a clue?
