I'm looking to upgrade my Bontrager Race Wheels. I don't race, and just do 20 to 50 mile rides. I am 165 pounds. I have been considering the following wheels:

1. Boyd Vitesse
2. Soul 3.0 sl
3. Easton EA90
4. Mavik Ksyrium Equip

I think I can buy any of these for $500-$700. Will any of these be a good upgrade from my current wheels? Any input would be appreciated. Thanks.
