Can't help you there - I've never used metal reels. Apart from Jobo, I've used Paterson ones (self-loading, those with the small steel ball), which are good.

With 120 format it helps to snip off the corners of the film before loading it. The reels should be perfectly dry before loading - otherwise it could be very difficult. If you're doing E6, you should not use the final rinse while the film is on the reel: remove the film and put it in a separate tray containing the final rinse. If you do use final rinse (detergent-like, foams a lot) with film on the reel, you should wash the reel very thoroughly afterwards. Same goes for Photo-flo for B/W films. It makes the reels rather sticky if you don't wash them very carefully afterwards, using hot water and an old toothbrush or something.
