In my search for a great slow speed ultra-fine grain film I ordered Rollei pan 25. I did this because the Rollei ATP is not out in 120 yet. I found this film to deliver very fine detail and ultra fine grain, the kind you can only focus with a magna view if you know what I mean. Ok, here's my problem on everyone of the rolls this has happen so I don't think it is a fluck, When I dry my film I place one clothes pin on top and then two pins at the bottom. When I release the bottom two pins, it really rolls or should I say springs. Is this typical of all Rollei films or is it just this film? I have also read that this is anti curl or is that just the backing? Sorry for so many questions, just thought I would pass on my experience with this film. For anyone that may be interested. I used HC-110 1:100 EI 25, 20 dg C, semi stand for 25 min. I gave constant agitation for 30 sec and then one soft inversion every 5 mins after that.
