I too find Patterson plastic reel is best suit for me in the 35mm and 120 world. I tried the SS reel, but it just not my cup of tea.
what I do is remove the 120 film from paper back completely, line up the reel's intake notch, and insert the film in just a bit, hold it there and use other hand to pull the film pass the ball bearing, you will feel the tension change. then the rest is easy, just start twisting the wheel to load the rest of the film.
anyway, light on practice is important and so does a dry wheel. Good luck!
