Actually, according to the PB 12.5.2 documentation, the highest supported version is 11, however, in moving to higher-than-supported versions of SA, I've never had any problems in PB, as long as I had tempered expectations about being able to take advantage of new features (sometimes it worked, sometimes it didn't). Personally, I think Andreas' suggestion is a good one.
If you're interested in SA 16, Breck Carter has a good article highlighting new features.
Good luck,
Terry.
