When you look at drop from saddle to bars from one model to the next, don't just look at stack height in the geometry specs. Many bike come with a lot of spacers under the stem that if not removed will leave a bike marketed as a "Race" fit just as relaxed as a bike marketed toward something else.

Trying them on is the best way to figure it out and having the experience to look for stuff like that. But also, maybe make certain you don't buy such an expensive bike that you can't afford another if this turns out to not quite be the one.
