Should be good. I've heard a lot of good stuff about this lens and camera. I had an SWC for a bit and that lens was pretty darn good; the Mamiya 43 is thought of just as highly.
The biggest issue I'd think about using this lens with the camera is that you have to focus with the internal finder and frame using an external finder. I do this with my Zeiss 21 and my CV 15 on my rangefinder. It's not the end of the world but it can be annoying every once in a while.
