45% incline. Very hilly roads. I was thinking of trying out the Vienna 1, Vienna 2, Trek 7.1, Trek 7.2, Specialized Woman's Vita, or Giant Sedona. There was another Giant in that price point but do not remember the name off hand. When I tried out the Trek 7.2 it was a 15" unisex frame and fit me pretty well. Though a woman's 15" would probably be a little better (I am only 5'2" with short inseam). I plan on trying out the Giant's tonight and the Vienna's tomorrow. I liked the way I sat on the FX 7.2 which helps me compare to the others.

What are the main differences between the Vienna 1 and 2?

I found two 2009 models of the Trek 7.x. The 7.1 was going for $379 and the 7.2 was going for $459.
