I'm looking to upgrade the wheels on my current bike, which right now has a Bontrager Race X Lite in the front, and a Bontrager SSR in the rear (don't ask why I have two types–bought it this way). I would like to upgrade the wheels, and I'm wondering first: If The RXL's are good enough that I should just upgrade my rear to match that front, or if there are better wheel sets for not much more than the rear (~$1000 max). If it's the latter, which wheels would you recommend for this price? I've looked at the ROL Race SL, ROL D'Huez, Mavic Ksyrium SL, or Zen Cyclery customs, but I'm assuming there are similar or better ones out there.
