Anyone who has used both of these care to comment on the staining characteristics of Rollo vs PMK. I'm very partial to the PMK staining characteristics, but I've picked up a Unicolor drum and reversing motorbase, and I'd like to use it for 8x10. Anybody using PMK in drums by modifying the ratio?

Fine as it is, I'm not interested in Pyrocat BTW- I'm after the green/yellow stain.
