What the other guys said OP....I gave you the economics in my previous thread. 5's are fantastic for the money. 3's which are 100 grams less weight are twice the price and also bombproof and excellent wheels.
I keep an eye out for 3's from time to time in fact because they are highly regarded.
Be sure to get the 11s Shimano hub if you are a Shimano or Sram guy.
