PMK is still my favorite go-to developer for all kinds of film, and I've both tried and have formulated numerous pyro tweaks from both categories
of "pyro". I don't recommend PMK for rotary drum dev, but for manual tanks and trays it's extremely reliable and predictable. I basically invert tanks or shuffle tray film once per 30 sec. I'm not suggesting that the other pyro formulas aren't excellent too. The Book of Pyro is worth it, even if you can easily get the same tech info elsewhere.
