So many great suggestions! Thank you so much!

So to sum up I have the following two groups. Can you tell me which wheel is the winner in both groups and whether you'd go with the cheaper or the more expensive ones?

Cheaper:
* Fulcrum Racing 5 (1645g) with tires and tubes - $385
* Shimano 6800 (1640g) - $350
* Vuelta Corsa SLR (1467g) - $330
* Mavic Ksyrium Equipe S (1690g) - $418

More expensive options:
* HOOPs 2426 Pacenti SL23 Build (1552g) - $500
* Fulcrum Racing 3 (1550g) - $468
* Flo 30 (1624g) - $498
* Mavic Ksyrium Elite S (1520g) with tires and tubes - ~$600
* HOOPs 2426 Elite Pacenti 23SL Wheelsets (1480g) - $580
