The hole size in paper music rolls has been debated ever since Ed
Freyer made recuts with small holes.  One argument is that because
most coin pianos playing the A or G roll have larger bleeds in them.
The small holes in the recuts would effect the instruments ability to
repeat notes.

Small holes at tune ten in recuts have to have an extra punch to make
the note the right length.  At some point in the recut roll with small
punches, the repeating notes will be one punch short and not repeat
well, while in the last tunes the recut roll will have an extra
punching.  This may or not make sense as I have always enjoyed the
Freyer recuts.

The most critical coin piano is the Cremona with the adjustable bleeds.
The lint seems to collect faster in these pianos than ones with brass
vents.  If you are going to the trouble to make a 6-to-the-inch
perforator, then why not make it correct with the larger holes?
