Yeah, the geometry is a very personal thing. I have a Specialized Tricross, which has a slightly more relaxed geometry than my Giant TCR Adv. I am comfortable on both, fitted on both (slightly different fit), and can ride hard on both. I do find that there is a little less fatigue on the Tricross over longer ride, while it's easier to push harder on the TCR.

Obviously, the bikes are configured differently, and there are lots of other variables (material, components, etc.). But bottom line is that a bike with slightly more relaxed geometry is designed to allow you to sit up just a tad more, while a more "racy" or aggressive geometry is more conducive to be more agile and sensitive in handling, while sacrificing a tad on comfort (relatively speaking).

If you're making a jump from a hybrid bike, the jump itself is a big enough change that you may not notice the difference between a more relaxed vs more aggressive road bike geometry. Either way you go, you can get a great bike, and not one is better than the other necessarily. It was just one thing I wanted SpinGirl to maybe ask about and be educated on before spending the money.

SpinGirl, seems like you have a REALLY good store there! Definitely get as much education as you can from the guys/owner at the store, even about things you didn't think you needed to know about yet. Well informed purchase are much less likely to result in buyer's remorse ;-)

Oh, another point - SADDLE! My wife hated riding her bike for a while because she was extremely uncomfortable on the bike. At first, we thought she just needed to get accustomed to the smaller bike saddles and having her weight on her sit-bones... (as'opposed to the larger cushy seats you'll find on rental bikes) but the discomfort never went away, and when she tried my bike on a trainer, she had no pains and no discomfort at all!! So we spent some time and energy trying out different saddles, and now, she has a women-specific saddle from Specialized that she loves. It made all the difference to her. Some shops are willing to do a saddle swap on a new bike... (or pay the difference if it's a much more expensive saddle) so you can ask about that too.
