I second the gratitude being offered. I'm now using pyrocat with Tri-x 320 at 2:2:100 in my Jobo and couldn't be happier. the prints, mostly from 5x7 and printed on Bergger VCCB, are the finest I've ever produced. My print exposure times have been halved, compared to Rollo Pyro and I am no longer concerned about uneven staining of the negative.
Unlike some of the "purists" you recognize the advantages of the Jobo and allows me to "steal" the results of your testing with very little adjustment. This really helps the weekend photographer.
