Yes, Daniel, I do much the same. TMax in Rodinal was my benchmark for a long time, then I managed to find a source for PMK Pyro, in which Delta 100 and Pan F+ seemed to do very well (but both films seemed to have intermittent quality problems). Then I tried DiXactol with a range of films, and most recently I have been using Fuji Acros 4x5 quickloads in PMK, which looks like a new benchmark.(posted 8424 days ago)
