I have that same wheelset from BWW. It was great out of the box. I put my rear derailleur in the spokes during a CX race and even that didn't break a spoke (though it did do enough damage to require a rebuild).
That said, my current favorite wheels are Velocity A23's with Ultegra hubs. I don't know if they are better in any way that I can actually feel, but the wider rims play nicer with wider tires.
