Simoni and Leipheimer.
Levi has a diesel sort of engine, like Simoni. Aren't amazing attacking riders, but get them going and they roll.
Except, Leipheimer can roll a flat TT as well. Anything Simoni gets out of him in the mountains, aside from an outright explosion/crack on Leipheimers part, will be made up twofold in the TTs.
Given the TTT, Astana will be a minute or more up on just about everyone else besides CSC, Highroad and Slipstream. Simoni and Di Luca are f***ed, right there.
