i currently roll Spinergy Stealth PBO's. the spoke technologie allows for a plush ride and they're bullet proof. i ride mine daily around pothole ridden metro detroit and i hit a goose last season head-on w/my front wheel @ 30mph (yeah, it was grizzley for both of us) but the wheels stayed true...
i'm riding a combo Red (crankset), Force (derailleurs), and Rival (brakes) set up. although it is not a smooth as ultegra or DA, shifts are lightning fast w/very short shifter throws. you can't beat the trickle-down technologie SRAM offers.
