That Continental Competition tire has the same tread pattern as the Contact Speed (formerly the Sport Contact II), so it should grip well. But it's extremely expensive and specialized, and the rolling resistance site indicates it doesn't perform much better than the much less expensive Sport Contact II, although it's difficult to compare tubs and clinchers, and the demands of racers vs we mere mortals.

I notice the rolling resistance site tested the Sport Contact II at the 700x37 size. Mine are the 700x32, wire bead. It's possible the narrowest 700x28 in folding bead might be a reasonable compromise in weight and rolling resistance in a puncture resistant and durable tire with good grip. I can definitely vouch for the grip and puncture resistance.
