I use several Kinderman (120) reels with no problems. If you are not already doing it, try cutting the corners of the lead of the film. While lifting the clamp some have a wire some a spike feed the film under and release. I prefer to slightly cup the film and roll the reel on the counter top. The film basically rolls itself on to the reel. It is not difficult to cut the film in total darkness. Practice in the light with a waste roll then in the dark.
