Thanks, all. The earliest (if I go with the CAAD9) I'd be bringing a new bike home is September, so hopefully I can get many, many more miles on my current bike before making a purchase. I'll see what I can do with my bike in terms of adjustments before anything else happens. If she doesn't fit, well, she doesn't fit. In the meantime, I'll keep an eye out for upgrades. I know BF was able to put Ultegra components on his bike because he got a good deal on the previous year's parts, so maybe I'll get lucky.

I'm going bike-testing over spring break--the LBS at home is a Giant, Cannondale and Specialized dealer, so I'll try the bikes out if possible. Heck, if I can get to a bike shop here and try some of them out, I will. I'll call it a "study break." Yeah, that's what it is...
