I assume you are having a problem loading 35mm film into developing reels. I usually use stainless steel reels (Hewes, Kindermann) and never have a problem - unless I drop a reel and bend it. Once a ss reel has been bent - forget it!

I just finished processing a couple rolls of 35mm on Jobo plastic reels. Once again, no problems. If plastic reels are wet or warped, they can be big trouble. With plastic reels, the shape of the cut-off film end that starts the film into the reel, especially the corners, can be important.

I suggest you sacrifice a roll of an Ilford film type that is giving you trouble, turn on the lights, try to load it onto the reel and see where and how it is hanging up.
