The good thing for Wiggins is that at The tour there are no time bonuses, and +10% gradients are rare. If you ran this years Vuelta field (with the same sort of form) over this years Tour de France profile with no time bonuses, I'm pretty sure Wiggins would win unless Froome beat him in the final TT.
Of course, the bad thing for Wiggins is that Contador, Schleck and Evans are a class or two above anyone in this Vuelta.
