If you can find one, a Pro-SD back will be newer, and give you the most functionality.

I note that KEH has a Pro-SD back listed currently. It is somewhat expensive, but they often don't last long on that site.

A Pro-S back would certainly be functional.

Did your camera come with the rotating back adapter? If it came from KEH, the listing would have usually said so.
