Absolutely..try out both.
Now how about THIS...
I was just told that another bike shop has a 51cm Aurora Elite that they just built up. Since the Elite is just a rebadged 07' Nova, the 51's standover height will be right in between the 50 and 53cm Aurora. Problem is, the head tube is almost an inch and a half shorter than the 53 Aurora, so I don't know if I'll be able to get the handlebar up high enough.
Off for another test ride..heh heh..
