I have been using the Mamiya QR device & plate inturn mounted onto an regular arca swiss plate (for use on my B1) on my Mamiya 7II. It works though, it adds a bit of weight and its rather bulky. It seems like getting an RRS or Arcatech plate would be a good idea.
I have no chance to compare either plate, was just wondering what everybody's thoughts were on the two.
Thanks a million!
