I seriously doubt that DiLuca would be able to "soft pedal" to victory, especially with 2 very difficult hilly TTs and a killer stage 15. Last year he got in Pink thanks to the team time trial and then only had to defend it.
I would be backing Schleck if he goes, and perhaps Simoni to go for one last hurrah (if he is concentrating on it and not doing track this week). Cunego is concentrating on the Tour no?
