Frank, besides the base, are there any other differences between the 5302 and the 2302? I've only seen so far people writing about the 5302, so I wasn't aware of the '2.
Using film since before it was hip.

No, the emulsion is the same, but the base DOES make a bit of difference in the image upon projection; the acetate is a bit more diffused looking and the polyester a bit more contrasty than the acetate (all other things equal).

We tend to aim for a total systems end gamma of 1.5 to 1.7 to allow for lowering of contrast via light scatter in the lens, the smudged projection port , the atmosphere and the dirty screen.
Just being pragmatic!
