I think Fomapan 100 is a terrific film, but I have run into more QC issues with it than with all other films combined. Mostly pinholes, which are mighty annoying when they get in the middle of your best images, but a couple of instances of what seemed to be strange emulsion defects all over the film area. I still shoot it in roll formats (and 9x12, where it’s usually the only game in town in the US), but I gave up on spending sheet-film money on it.
X-ray film is challenging to handle for sure. I eventually found that my best way to develop it was inside a gallon (~4 litre) plastic bag, so I wasn’t agitating it in contact with anything rigid that could scratch it.
