Kind of depends on the bore length to begin with me thinks. If, as Petrof
themselves say do, you vary the bore length to match string height you have a
different situation then if you have, as in this case a standard out of box set
of replacements... or what ? Course when the first shoe shine reshaper comes
along...... :)

Interesting enough point though. We see curved string planes dont we, and rather
randomly uneven ones as well. Can make for some interesting hammer lines that's
for sure :)

Question though, as long as we are on about this. Some pianos have a thicker
cushion for the hammer rest rail in the bass then in the rest of the piano to
compensate for higher shank position there (when so configured). So, what
difference would that extra 3 mm or so distance between the rest cushion and the
shank mean ?
