I used a lot of Agfa's Vario-XL in 120, when it first came out. On the boxes it gave a speed range up to 1600 ASA, but I always used them at 400. The film never struck me as particularly stable. The colour of the actual image on the processed negatives varied a great deal from blue to a purple-ish colour, irrespective of whether I had them developed by a lab or did them myself in C41. Worse still, I found even after just a couple of years the colours were changing, and not particularly evenly. As I never had cause to reprint any, I've no idea whether they were still printable. I ended up with a large quantity of the films which I never used, as I was unsure of the stability. There are probably a few rolls at the bottom of the freezer even now!
