I don't own anything super high end, but I have lots of 531 bikes of various configurations. I find that on the whole sport-touring geometry and relatively lightweight tubing serve me best in the combo of comfort for many hours in the saddle and agility/speed. Pure touring bikes don't work for me and bikes with racier geometry don't work for me in that they don't match the kind of riding I do. That's why early 70s road bikes make up such a large part of my herd--they have that sweetspot.

That said, yesterday I did a 45-mile-ish ride on my Fuji S12-S and was loving it the whole time. A frankenbuild with SunTour Superbe brakes, Shimano levers, Stronglight 99 crankset set up as a compact double, Shimano Crane mechs, Weinmann concave rims and Panaracer Rolly Polly tires, and a very worn Belt saddle. I have lighter bikes, and I have flashier bikes, but the Fuji never fails to please.
