Good for you, Ace! Like many of us here, I've also felt that twinge of buyer's remorse after slapping down a wad of hard-earned bucks for a snappy new bike. And at least once, my fears were confirmed--but that was my first adult bike, which, as it turns out, was too big for me and the salesman either didn't know or didn't care. OTOH, I sold it easily after only riding it for a few months and my next bike purchase was a Terry Symmetry, bought from another shop, of course, and after checking all the measurements and taking a good long test ride.
It sounds like you're doing this right--getting fitted, dealing with an LBS that you've built an honest relationship with. I can't speak to the diff between a hybrid and a road bike since I didn't start out on a hybrid. But I will say that the difference between the too-big road bike and the just-right Terry was vast, and too some getting used to simply because it was so much more responsive. So when you start riding your new bike, give yourself plenty of time to get used to it.
I've been eyeing those custom steel Serottas myself--is the Coeur d'Acier that you're getting? Yummy! We want pix, as soon as you get her home!
