I can only speak to the Scott's in general part of your post.
I have a 2005 Scott CR1 Pro with stock setup (Campy Centaur).
I Love, Love, Love, my Scott. The frame is all cf, big tubes, stiff. She's a fast bike, a little twitchy, great on climbs. It's just a very good quality bike.
Let me know if you have any specific questions.
