We're not all carrying excess bodyweight, I'm 6'0" and 63kg, and body lightness isn't always the best way - the lighter you are and less upper body muscle you have the more likely you're going to break yourself in a crash.
I think using aluminium is a good idea and do that myself. It's not that hard to build a light alloy bike. The amount of snapped carbon you see after even a minor pile-up in a race is enough to put me off until I can afford to throw carbon frames away. A £300 Planet-X carbon frame would be one thing, but a £3k S3? No thanks!
If you're going to use carbon, use it where it's going to make a difference, like forks. It's crazy the amount of people you see racing carbon bars - they are barely lighter than alloy bars and the first thing that are going to touch down in a crash.
