Of course if it did fit I'd be wasting film, but the RB 120 backs are going for a premium these days since there is so little 220 about.
Also, from my experience with several, the rb67 backs seem to be a weak point in system, both for light leaks and mechanical gremlins.
There's why you gotta do your research and not take my advice! I didn't know the RH-8 didn't work on the RB. I only have the RH-12 which I tested and it worked Perfectly. No light leaks and I shot in bright sunlight and didn't even use a dark slide.

I have both a 120 and 220 back. Both are Pro-S. I've never had any problems with them. I'm sorry to hear about your issues though.
