I started with ep/2 many years ago now...
I run ra/4 6-8 times per year, usually in a run of 3-4 nights to get me caught up. the first night is usually getting though the backlog of contact prints.
I actually do it while getting other chores around the hose done, since once the roller processor is up to temperature it is a print every 5 minutes between filtration adjustments, or as fast as I can feed them in once things are in calibration and balanced.
generally 8x10, some 11x14, and all sorts of whatever I want that is max 12" wide and will thus get though the processor. I do have a drum for up to 20x24, but no paper that size any more. I still have all my drums and a pair of roller bases for when my roller processor dies and I have a deadline, but oh, the Fujimoto makes life so convenient.
The freezer has Fuji CA 12" by a few hundred feet, 5" by I think 600', and kodak Portra B&W that is not quite black any more. I use that for reversal contact prints of e-6 slides in contact filing pages for indexing purposes. Also several flat sheet boxed of mostly Endura and Supra, and bit of Portra.
