It was mentioned above that the flap on the film holder can get in the way during loading. It has a tendency to spring up. I had been using a finger to hold it out of the way. I have discovered that this is much easier if the holder sits at the edge of the work surface, or on a book or similar object. If working with a flexible changing bag, not the tent type, the book can be placed under the bag. For the tents, it has to go inside, and in a darkroom you can simply use the edge of the table. It may not be a major issue, but I'm always wary of the film sliding over the flap and being damaged in the process. This technique has helped me avoid any contact between film and flap.
