One area not receiving much mention in this current string on tracking
systems is the precision or lack of same that the tracking system
positions the roll during reroll.  I've noticed on at least one old
Ampico upright and on Ampico B's that there's provision for the
tracking system to center the roll at the same precise and adjustable
position during the reroll.  This may be true on all Ampicos, I don't
know, but I do know that there's a definite lack of precision in
centering the roll during reroll with most roll-shifting tracking
systems.

Mis-adjustment of the rewind lateral roll position with the Ampico B
can selectively and reliably shred the roll against either the left or
right roll flange.  Careful adjustment of the lateral position of a
roll possible with a tracking system capable of positive and precision
lateral roll positioning during rewind has proven to very much minimize
the edges of the roll rubbing either flange and tearing.  Many good
straight rolls will often rewind from beginning to end with the paper
seldomly even brushing against the flanges when everything is adjusted
right.

Even most of the less precise systems have provisions for adjustment,
the fishing pole types being the exception as they lock at what ever
position they're at when the player is shifted into reroll, so this is
something to look at to help preserve your rolls.
