I have used Tech Pan, and Gene Crumpler can give you an earfull on using it.(posted 9055 days ago)If pictorial results are what you are looking for, use Technidol, and nothing else with Techpan. Techpan has an inherent high contrast to it, and I mean an extremely high contrast. Technidol is one of three developers which will tame it, and the other is very dilute Xtol. Follow the directions included with the Technidol developer, and you'll have some nice negatives.
If you want to use PMK Pyro with a slow film, go with Agfa APX 25 or Ilford Pan F Plus (ASA 50).
