They felt nice, but I have yet to notice any magical superiority that some claim they have over GP4000s/Attack/Force. That said, it was my first ride with them and lots of flat and straight ahead, so who knows. The profile does seem considerably smaller/rounder than the 23C Contis/Michelins, so I could see how some would feel that they're a little more confidence-inspiring in turns, 'specially on 19mm wide rims.
