You could try using Kodak Profesional Ectachrome 200 ASA (color print
film)and have it push processed to 400 ASA. This seems to require a
different development process though.
I've had 400 ASA film push-processed before, with excellent results. 

I have noticed that the Kodak Ectachrome ASA 400 gives very good results,
however, with minimal graininess! This film also seems to be more blue
sensitive.

Whereas, Fujichrome ASA 400 seems to be more red sensitive.

Overall, I like the Kodak Professional Ectachrome 400 ASA the best. It
costs alittle more, but the greater contrast and minimal graininess is
worth it.
