I tried some Portra 800 for the first time the other week (wouldn't normally buy it but 5 rolls came with a bulk purchase so I shot 'em at a family gathering) and developed it on Sunday afternoon. It looked OK coming out of the dryer and I'll see how it stands up to scanning in a week or two*. I shot it at EI640 or so and definitely got more speed from it than I do from 400, contrary to a couple posts here.
Also shot some Delta-3200 (similar situation - nice film but I rarely want to pay for it) at a night parade in my C220. No idea how that went yet.
* my backlog is getting stupid: 32 rolls in the cupboard on Sunday when I thought I'd have an afternoon free to run the Jobo, and processed 18 of them (C41). Need to do a B&W batch soon too. And scanning; I get through about a roll a night feeding my Nikon 8000 one frame at a time so that adds up in the worst possible way. And that's just the film backlog; my printing backlog doesn't bear thinking about, particularly given my recent losses to user-error with Sistan and needing to re-print a pile of B&W negs. I'm about 3 or 4 years behind on wet printing my C41 keepers, i.e. I'm printing at about half the rate I'd need to to keep up
Going to need more automation I think, but of course spending some time calibrating things is time that I could have made probably 5-10 prints in.
