Is Basso being too ambitious?

Ivan Basso, ambitiously going after both the Giro and the Tour, is back in action in La Fleche Wallonne for a CSC team seeking their third straight victory in a spring classic.
Team CSC is looking impressive and a clear favorite for both tours, but is Basso being too ambitious, should he just focus on the tdf and use the Giro as training? (This is what Ullrich is doing). Will Basso's decision play into Ullrich's hand in the tour de France? Only time will tell, but Basso for sure doesn't lack courage.
