Thomas, I use it mostly for LF, thought I'd give it a try with the Acros (35mm). I couldn't find much on the MDC for it, so I guessed (based on similar times/D-76, my other dev). I print via Omega D-6 Pro Lab or contact print. I shoot mainly 4x5 and 5x7, so it's very economical for me, especially with rotary, 200-225 ml per 4-4x5's or 2-5x7's in a Unicolor drum. It really shines with Fomapan films, and the old Shanghai GP-3. Price initially seems high, but since you need very little, it is very cost effective. I used to use Pyrocat-HD, but wanted to try this, like it more. I use graded and VC papers, no difference in tonality. I've been reading some folks can't get a "proper stain" using Ilford film, that is of no consequence, IMO it still makes for better printing negatives than most developers I've used over the years. I even like it for T grain film, Delta pops with it, even though I'm not a fan of Tabular film except Acros. I have a pile of Acros 120 in the freezer, I should probably start using it again.
