I remember Royal X Pan which, like Agfa Isopan Record and Ilford HPS, was a "superspeed" film with normal tonality, low to medium resolution and coarse grain. As I recall, the recommended developer for Royal X Pan was DK-20, which always produced a lot of dichroic fog for me - in Rodinal, on the other hand, Royal X Pan was a dependable grain-effect film, rather like GAF 500 in color.
