I have been really happy with the Roval Fusee SL 25 replacement for the EL28. I am 185 lb and have had no issues with the SL 25 wheels. They are quite true and the spoke tension is near perfect. The bearings are exceptionally smooth.
My older bike had Mavic Kysrium Elites. They were a little heavier and less aerodynamic than the Roval SL 25, but I suspect they will handle a heavier rider quite well. I thought they were excellent wheels at a comparable price to the EL28.

Based on your experience, I am really happy I didn't have Specialized do a factory rebuild. If you get the Rapides, please post your experience with them.
