I normally won't touch the stuff as I find it's very inconsistent if you do colour printing and consistency is very important in printing.
That said, I did get ten rolls of Agfa Ultra 50 a few years back which had probably been stored at room temperature. The film was exotic enough to be worth a stab and it's held up pretty well over the years. I'm glad I gambled on this film as the results are incredible. I've never seen such saturated reds and I'm exploiting this look to make sure each roll is well used.
