I'm about to head off for a photo holiday in India and I'll be including an RB67 Pro S with a 220 back.

I've never used the 220 before, it's always been 120.

The question I'd like to ask is; has anyone had experience with 220 roll film in the field?; is it more sensitive to light than the 120 packed rolls, with reference to loading it in sometimes unavoidably bright conditions.

Also I'll be taking all my film out of the packaging for hand inspection through the X Ray machine, is the 220 going to fog out by being occassionaly exposed to whatever lighting exists in the airport.

Greatly appreciate any advice, tips or anecdotes.
