I am late to this discussion and you might have already purchased your Jamis Renegade but if not here is my 2 cents.
I am right at 5"7" and this past spring I purchased a 51cm Renegade A1 and it fits perfectly. A 54cm I think would have most likely stretched me out too far on the bike. I have ridden many miles on mine now including paved roads, gravel roads and hard trail and am happy I got the 51cm over the 54cm. Your case might be different but the smaller frame works for me.
