I have used Patterson tanks and reels for 90% of my film developing life and have never had a problem with them, there is a very simple trick to Patterson reels, and one which would apply to any plastic reels, take a sharp pencil, run the lead around the groves of the reel, load film, film slips in like a hot knife though butter, I have been doing this for more years than I care to remember and I have yet to have a film stick.
