I'd err on the side of smallness... you end up with a slightly lighter and tighter frame (front wheel tucked in a little more, better weight balance), and there really isn't any downside. Put your seat at least as far back as KOPS, then position the bars for comfort... which may take a few tries. If your seat is far enough back then you'll have little weight on your arms, and a long reach should feel comfortable. If you like a high bar then get a 17 deg stem and flip it up.
