it has a 4th layer of dye which is supposed to help with different lighting situations such as flourescent lights. It is also available in the fuji press 800 and the consumer superia 800 (same thing as fuji press and just renamed). I would just shoot the consumer fuji 800 . Do this if you're using an f2.0 lens or faster so that you can stop the action, if not I'd suggest 1600 speed, 800 pushed a stop, or high speed b&w.
