I need advice for a good tough wheel set. I seem to be hard on rear wheels and have broken/lose spokes problems putting a crimp in my riding time! Usual put in about 3000 miles a summer, wt. 215, Ht. 6'1". I doing a lot of climbing but I'm stay in the saddle type. Riding Neuvation R350's now, friends say the Ksyrium SSC-SL or Elites is what I need?? Maybe just a good rear will do?
