Provided he finishes, sprint I see going to Cavendish. If he does not then I will go with Bennati. My first choice ideally would have been McEwen, however, I don't think he plans on finishing in preparation for the Tour
I think either Soler or Contador will win the KOM jersey. If contador isn't feeling it for the overall I think he will change his focus on this.
For the overall, I don't know. I think Kloden is the favorite at the moment, but I don't want to rule out Simoni or Di Luca. I also think RRRRRRRRICARRRRDO RRRRRRICO will do something exciting, but I think he will crack before the end. Menchov will also be in the mix, but not the win.
For the young rider. I don't know their age... So who knows, but I believe CSC is focusing on Sorensen, so I will put my money on them being a good strong team. Or for a second choice maybe the youth will go to Liquigas
