JHA may be recommending that JH16 is the better foundation, but the JH13 seem perfectly capable of the task. I wouldn't use that as the criteria, I'd use the criteria on whether or not you can really afford it (I know, a lot of times when I say, "pushing the budget", what I really mean is, "it's probably more than I should be spending right now, but fuck it", when in reality I should find another alternative).
