Shamus, please stop posting your Colnago as it is far too beautiful and causes my heart to feel a certain degree of sadness. I think comparing one beautiful steel frame to another is very tough regardless of the builder but this Colnago is a classic example of European excellence.
Aluminium and/or carbon bikes are clearly superb but on aesthetics steel has to win (or does that just betray the bikes I loved when I was growing up?).
