I am 5'2.5" with 29" inseam and LOVE my Epic Comp. If you want they rent them, I don't think they rent the small but I tested the hardtail on the trail and it was a very comparable fit. There are several of use that are rather short that race for BSS on that bike, it is snappy, fast and fabulous!
I was very concerned about the standover looking at geometry charts and that was quickly put aside when I rode the bike. I think you won't be disappointed with any of those on your list but I don't know anyone who doesn't like their Epic Comp.
