I can't load plastic reels with 120, be it Patterson or Generic.. I mean, I can get the film on there but I end up kinking the film pretty badly. I've smashed more than one reel before.. I'm thinking that high-humidity might have played a part in my troubles.
Either that or gunked-up ball-bearings.

I liked the jobo 120 reel, the real big/wide ones that also take 220 I think.
Although I don't know if I was ever loading it properly; I just 'pushed' the film in. Worked well for me though.
