I ran 6 sheets of Arista EDU this week-end. The exposures looked fine and the holder seemed to be reasonably easy to use. I did notice a few faint scratches on the back of one of sheets. I guess some cleaning of the septums is in order. Is PEC pads and some isopropyl alcohol OK?

Also, some septums have a little bend at the end where it gets inserted into the holder. Is it wise to try to straighten them out, or is it better to leave them as is?

I always shoot two sheets of film - one color and one B/W. I think for the trip, I'll use grafmatic for b/w and regular for color (or wise-verse). This way, if I screw up, I won't lose much...
