Pust the film into the center locking it, then bend as above while turning reel with other hand and it just flows on.
I always put the end of the outer wrap at 7:00 coming from 12:00 clockwise. If you go in the wrong direction the film will not load and you WILL kink the edges making loading impossible. Retry from other end.
Practice in daylight with scrap roll.
Do what works for you. I grasp the film between my thumb and middle finger, using my index finger placed gently over the middle of the film. That allows me to keep track of the bulge of the film and if helps me keep the film in the grooves. I lift the index finger when pulling my hand back for another grip. I always pull a couple of times, back and forth, testing for that small amount of play that tells me it isn't binding anywhere. If it's binding, I pull it out and start over. If you haven't already, sacrifice a roll, or use that one if you haven't cut it, and try practicing in daylight a few times, watching what you are doing, the in daylight with your eyes closed. After that it shouldn't be too difficult.
Sound complicated, but it gets to be like riding a bicycle; you learn and then never forget.
