Fair enough, EXCEPT there is the occasional situation in the low tenor and bass where the agraffe to tuning pin string length is so short that you either need an especially high front bearing (making it even more difficult to thread the wire up and over), more than less coils (my late entrance to this thread) a shorter pin height than the neighbors, or a negative pin angle to allow the last winding to be tight up against the rest. As for pin depth, it is my experience that the deeper the pin the greater the torque. I would be interested to hear others' experience with this. Perhaps my perception was simply comparing "flag pole range" to "non-flag pole range."
