Th Ruby is a women's specific bike (like the one I have) and seatpost angle or not, I would guess than any bike with an 80 stem that makes you feel "stretched out" is too big for you. Judging from what you have written, I don't have a lot of faith in your fitter. A 3rd party fit is a good idea. If you have the time, I recommend you taking down to Surf City in Huntington Beach and talk to Mike or Sean.

Regardless, the LBS should make you happy. Specialized stands behind their product and if your LBS gives you trouble, I would think it's them and not the bike that's the biggest problem.
