A lot of people that "size down" end up feeling cramped on the newer geo bikes if they spend a lot of time in the saddle - which a lot of us do.
Also, you will be more over the BB than behind it with the steeper STA, which is good for steep climbing, but can take some getting used to on flats/rolling for some people.
