I don't use a Jobo, but currently use TX320@ 250, and develop in Pyrocat HD for 12mins 1:1:100. This gives great negs for silver printing, just a tad thin, but just how I like them. Of course this would not be any good for PT printing.
Have you thought of Max Pyro? I got some from Bostick and Sullivan a while back and actually processed some FP4+ in it by mistake (thought it was P-Cat HD) and the resulting negs were..er, quite dense and contrasty...perfect for PT printing I would imagine.
I am going to do some Van Dyke Browns soon, and I'm sure this developer will give the results I need.
