OzJohn:

You're absolutely right.
I still can't believe I said that...

Reviewing my sketches, I was exploring the possibility of splicing a 15~16~17 exposure roll, since two 120's end-to-end would never fit onto a 120 spool. I was even toying with the idea of ordering a bulk roll of 120 film and winding a 19 exposure roll since my cameras would really squawk with a loosely wound 220 roll.

I still can't believe I said that...
