The formula I posted shows bisulphite, while a Kodak formulary that I have shows metabisulphite. Kodak also suggest that D-25 is used at 25*C (77*F) and to use the development times for undiluted Microdol-X for 20*C (68*F).

I don`t want to make it, I was simply curious how it performs with modern B&W films, hence my question if anyone has used it.

Sorry Ron, but I don`t see the connection between D-23, D-25 and Rodinal.
