Tri-X in Microdol-X 1:3 at ei 250 was my standard film/developer combination for many years. I also used quite a bit of Plus-X in Microdol-X 1:3 at ei 64 with excellent results. I have switched to Ilford 400 Delta in XTOL 1:1 at ei 320. I would not hesitate to recommend Microdol-X to anyone.(posted 8679 days ago)
