Anybody have any experience with these? With Campy drivetrain? I can get a smoking deal on a set, but I've read some reviews that say the shifting is sub-par, and the chain has a tendency to drop off with downshifting. The main advantage of these over my current Records, is my Records are still the old square taper with the internal bearings. I can get a new set of the FSAs for 100 bucks at a place where I have a gift-card already. Think it's worth the gamble?
