I tried T-max 400 for a while (8 x 10 sheet film) and was amazed at the look of the negatives developed with PMK Pyro (they looked fabulous). Was there a difference in the look of the prints between something like PMK and HC110? Hard to tell since my enlargements are only 4x at the most. I never tried it with T-max developer.
However, I've heard from some people that Pyro with larger sheet film developed in trays might give different results that roll film in tanks.
