I shoot this film as my current standard film, my current toughs are that it's not true ISO 400, since shadows and highlights both are very sensitive.
I develop in D76, which gives a fairly high contrast (even with low contrast lenses, such as the coll. 'cron).
The grain is very fine, and is well suited for scanning.
The PET base dries perfectly flat every time, and is very tear resistant. It is however sensitive to light, so be sure to load in subdued light. I had a very peculiar issue, where the light seemed to follow in the base far into an IXMOO cassette, spoiling the first 4-5 frames.
Next up, I'm going to try pulling it to 200. Also I'm planning on souping it in microphen, to draw some more shadow detail out.
