I bought SS Hewes reels for 35mm film a while back, and it works great. None of that sticking/murder marks that I get with Paterson reels. So I get the SS reels for 120 film too. Out of 5 rolls developed, two have unwound completely from the reel while in the tank. One unwound a little bit. Those completely unwound have bad scratches and are ruined. What am I doing wrong? How can the film just unwind? I've practiced loading in the light, and I think I got it right. When loading in the dark, everything feels right, too. The only thing I can think of is my agitation pattern. I do a little "twist" as part of my pattern, to create a "tornado" in the tank. This has helped remedy some issues I had with uneven development on the edge of films. Is there something obvious about loading SS reels that I might have missed? Anyone else who's had problems like this? Thank you for any advice!
