Hey Bill,

About a year ago I was using Supra quite a bit.
Compared it to LE 400 and Fuji 800. It beat both of
them on anything longer than 30-40 minutes on red
response. For blue response Supra was slightly better
than Fuji and way better than LE. 

FWIW, all films were unhypered and this was a year
ago, who knows what has happened to the emulsions
since. Supra will keep on sucking up light for at
least 2 hours, so there is little reciprocity failure.


My 2 cents,
Alan
