Here's the question, xtolsniffer: You enlarge up to 12x16. Do YOU see a difference in your prints?

If you don't see a difference at the size you like, then I'd say you have your answer. However, I know there can be many reasons for hauling around the RB67 (I have a Pro-S and it's my main shooter!).

Shoot what's most fun to you. That's what matters. That should be justification enough!
