Paterson are ubiquitous and beloved by many of us. I have umpteen of their tanks and reels. When it comes to easy loading of 120 film, though, I much prefer a Jobo tank. It NEVER snags. Unfortunately mine only holds one roll, so if I need to process a lot of film I use a Paterson multitank. Much more exciting and unpredictable. Make sure they're dry, and occasionaly split the reel and run a pencil round the groove of the spiral. The graphite make them just a little slippier to load.
