I have not. But I have both Pyrocat HD and Catlabs here and 16 minutes (with the film exposed at 200) seems like a good starting time based on suggestions I got from a different thread. Alas, I had some photos I wanted for sure on those rolls so I chickened out and used xtol.
If you try it, please let me know the results! I'll do the same on the next roll I shoot.
Just to follow up:
I put two rolls of Catlabs 320 pro 120 film with my Tmax 400; same tank, same time.
Exposed the Catlabs at 200.
14:30 time 1:1:100
Just eyeballing the negatives drying next to the Tmax 400, the expose/development seems right on.
Nothing scientific; just comparing negatives with some LED backlight.
Stain seems about the same as well.
Have not printed or scanned yet.
