And even if you have a vacuum back like I do, you can't get some films
in 220 size - Provia 400F being the main problem for me.  However, there
is a way to cut the paper backing out of the middle of the 120 roll in a
changing bag to allow using it with a vacuum back.  It's a bit of a
hassle, but with practice you can get good at it.  Fortunately E200 is
available in 220 size.
