I use TF4 for all pyrocat, pmk and prescysol-ef(very much like pyrocat imho) negatives and have been happy. That said, I ran out for a week and took a chance and processed pyrocat-mc negs in hypam(ilford) and saw no visible difference in stain or quality of the negatives. Since then I recieved my TF4 and returned to it. The TF4 is a bit costly comparatively speaking but maybe a little more piece of mind since I don't want to spend time doing exhaustive test to see if it matters
