Need some opinions here. I have a Klein Quantum Race, Integra and 105 components. I like it, but thinking about an upgrade. Looking at picking up a CF Jamis with all Dura Ace and Mavic wheels, or just picking up some Mavic Krysiums for my Klein. I can get the Mavics for about 50% of retail, or maybe sell my Klein and pick up the Jamis for 1800. Any thoughts on the wheelset and\or Jamis bikes would help....
