I built my own wheels and never looked back. DT Double Butted Spokes, Mavic box rim (MA40) and 36 H XT hubs. I followed the Bicycle Wheel Book as a guide. 12,000 miles and not even a touch up needed. I took a chance and ordered a set of Performance Wheels , 32H Ultegra Hubs , DT Spokes and Mavic Open Pro rim. I did retentioned and true them myself and they have been just fine after 5500 miles.
