Interesting thanks, hadn't realized, if I could change anything I would simply wish that the RB backs would not have foam rubber but simply like traps like the RC Pro II do, I would probably switch to the Arby anyway because I like the fact that you don't need a battery with them. But I do like the interlock cocking the shutter and the mirror and rotating the film to advance it all in one movement option that the RZ has that the RB does not.
