I'm thinking about getting a roll of 90mm FP4+, which is probably close enough to 122 to use in my Kodak 3A, but I'm not sure how I'd develop it. Even the idea of threading 116 onto a spool sounds hard ( although, honestly, I never have any problem at all with 120 and sometimes struggle with 135.... ) I'm sort of afraid to try "dip and dunk" with a photograph that I care a lot about!
