I haven't had the spare cash to buy 5 rolls of Supra 400 to try
it (you can only buy 5 roll lots in Australia).  It's supposedly
"optimised for scanning" whatever that means.  I've used Fuji
Superia 400 and if it's properly exposed in bright daylight
conditions, the apparent grain isn't too bad.  I've had to use
400 to get sharp photos while flying in ultralight aircraft.

I've shot quite a few rolls of T400CN.  On colour paper it *will*
have a sepia tone to it.  XP2 seemed to come out bluish.  It has
to do with the base colour of the emulsion and how the colour
paper interacts with it AFAICS.  My local lab can print T400CN
on B&W paper in their minilab, but of course it costs more, and
neither paper gives results as good as "proper" B&W paper.  I just
get the prints on colour paper, enjoy the tone and try to guess
what it will look like on real B&W paper. :)
