Hi. I have some very old Plenachrome 620 that I'm trying to load and it simply won't load. I have tried multiple reels, both ends, cut the very tips off, etc and it still won't load. It gets hung up after a turn or two and loses track. The film is extremely curled. It is also very fragile. Any ideas? Load it base down? I have this loader thing called a "Lasagna reel" which is for 35mm only but it may provide enough spacing to let the chemistry flow between. Good/bad idea? Thanks!
