I haven't tried PMK with Pan-F. I stopped using Pan-F because it became hard to get where I live. Now, all films are hard to get where I live and I order everything online now, so I should try it again. I loved Pan-F in Rodinal 1+50, it was a great combination.
I've gotten great results with PMK and Tmax 100 and 400, Tri-X, FP4, Fomapan 100, and Fuji Acros.
