I guess what I am concearned with is the standover height...

On the large the standover height is like 29.something" and on the small is 28.something". Now, is the standover height measured closest to the headtube I wonder?

I'd like to stick with the short do to the shorter wheelbase....but if it's going to end up being freakishly small and I am going to be all cramped up on it...well.
