I'm processing my TMX in expert drums in Pyrocat 2:2:100, 1 liter of developer for 10 min at 68 neg shot in sunshine. My rotation speed is "3", whatever that translates to in RPM. I may overexpose by your standards. I rate TMX at 200 and place the shadows on zone IV with my spot meter.
I'd be very interested to hear your results. I seem to print well on AZO Grade 2. Though I'm about to give up on 8x10 contact printing and go back to my favored 5x7 Tri-x enlarged to 10x13. But that's a story for another day...
