Nev, I've been working with the latest releases for some time and it's really not living life dangerously. After 20 versions MC is stable and the incremental changes are not that much of a step into the unknown.
I'd suggest in this case that you stay with build 48 and see how you go. If you strike a problem, let us know here and you've always got the backstop of rolling back to a previous build. If you're happy to wait, fair enough.
