I remember a Kodak publication/information sheet about tmax 100 and Pan-X and Kodak recommended Tmax 100 shot at 50 processed in Microdol-X 1:0 as a 'direct replacement' for Pan-X. As far as I can tell in comparing the few old rolls of 120 Pan-X I still have left, Kodak is correct: thats the very closest I've ever gotten to the creamy tonality of Panatomic-X, and of course the grain (what you can see of it) is different but the tonality and excuse me, 'glow' is there. Try it.
