k - have you tried any Giant bikes?
I think they a little bit more price friendly. I actually tried the Trek carbon bikes and I really, really wanted to love it because I really liked the LBS and how they treated me.. but I just couldn't do it. Just didn't feel right to me.
I kinda swore off carbon, until another LBS told me to just try it for the size. I really loved the Giant carbon ride.
Anyway, they make WSD (which are actually designed by women) and obviously non WSD. I'm riding the non-WSD since they didn't have WSD when they made this bike.
I've also heard Scott is nice but I haven't ridden any.
I agree with Melissa though maybe you want a tri bike...
