Michelin Pro3Race, Conti GP 4000s, or Conti GP Attack/Force.

I've long used the Pro2Races, but recently picked up a pair of the Attack/Forces (when I couldn't wait any longer for the Pro3Race to come out). I admit I really like the feel of the Attack/Forces.

I'm not entirely sure if there are significant differences between the 4000s and the Attack/Force - there are subtle differences, but I'm not sure if they really matter much.
