I have a Trek 5000 (TCT) which is basically the same as the Madone you have - it is definitely a blast to ride. Though I'm thinking of selling her to rustle up funds for a steel ride. Can't really clamp much on to joyride around with my baby girl in tow when it comes to the carbon bike.
Enjoy - I think they're fantastic and a great step up from the 1000!

"I rejoice every time I see a woman ride by on a bike. It gives her a feeling of self-reliance and independence the moment she takes her seat; and away she goes, the picture of untrammelled womanhood."
Susan B. Anthony, 1896
