I was having trouble loading 120 onto a Patterson reel until I loaded it from the end of the roll first, using the tape as a 'stabilizer'. I was a little worried about the last frame (#16 as I'm using a Pentax 645) but it came out fine. Or, you could just put a piece of masking tape on the leading edge of the film, but not sure if masking tape would react with developer/fixer.
