which is to say, we shouldn't trust the ad copy saying that disc-brake is faster
i don't know about your riding style and attributes, but i was the type to go for any little aero advantage possible back when I raced. I couldn't accumulate points from sprinting, so I had to get away solo or in a small group, and aero helps there.
The S2 was ahead of its times, and i'd venture that few framesets represent a significant upgrade over yours (earlier S5 being one of those)
only minor quibble is that you can save a bit more by using an aero road brake such as the Tririg Omega
