On impulse, I bought ten roles of Arista Edu Ultra 400 (120 size) after not using it for over a year. I developed the first roll last night in Diafine and was quite surprised to see that it had no appreciable . The only downside is that they are making the film a bit shorter. I was shooting it in my Zeiss Ikon Nettar 515 (6x4.5) and there was less than 1/8" of blank film after the last 16th frame. I usually have enough of a margin to clip a couple of clothes pins to put some tension on the film while it dries.
