High speed film for scanning

I've been looking for a good film to use for high speed situations -
e.g. a night baseball game or other sporting events and have good
results to report. Fuji Provia 400 (RHP III) pushed to 800 does an
excellent job - very much better than Fuji 800 NPZ. The grain in NPZ
is objectionable to me, even for small enlargements. In comparison,
RHP look grainfree at 100% in Photoshop. Its not quite as sharp as the
100 speed Fuji slide films, but certainly better than anything else
I've seen at 800 ASA. Fuji's datasheet mentions that it can be pushed
up to 3 stops, so I plan to try some at 1600 and maybe 3200 when I have
a chance. Any other films I should consider?
Peace,
