Amen, brother! Back in my racing days, I rode a (2nd generation?) C'dale "criterium" bike for a couple of years. Felt very light, responsive and stiff, but I was on a first name basis on every ripple in the pavement. Switched to a steel frame (Eisentraut Rainbow) with almost identical geometry, which kept the snappy feel in terms of acceleration and handling, but took the edge off road irregularities. Like switching from a pickup truck to a european sports sedan. The really interesting thing is that the 'Traut climbed just as fast (subjectively, anyway) despite being a full pound heavier. I'd still be riding it if not for some yoyo in a pickup truck making an "improper right turn". )-;
