			il cobra. because at his best,he looked like the only person in the world who can upset alberto on the climbs.and when you think that this year's giro could have been the revenge....
		
		
	 
In a Giro where Contador was riding with a cracked elbow (ala like a certain rider at the 2010 Tour that I won't mention), not ideal preparation, with no reconnaissance of the events climbs. I personally can't put Ricco in the same class as Contador based on that particular Giro alone. Had Ricco showed the same level of climibing prowess at the Tour versus Contador and others till the end of the event I would then give him some consideration but for me he remains an example of a talent which we may never see the best of.
I'm going with Purito (as a pure climber) and Anton for the future as someone else mentioned earlier (sorry can't remember who to give credit/will edit later).
Basso is close with Purito and based on the disclosure of some type of illness being the cause of his less than stellar recent performances, I'd have to give him the nod over Purito in terms of overall climbing. 
I'm flip-flopping here but I really believe that Rodriguez is one of those late bloomers who will continue to get better in the grand tours. His Vuelta performance last year for me was quite impressive for 2 reasons: 1. It was after his first appearance at the Tour as team leader, finishing in the top 10 and a stage win, and 2. He seemed to get a 2nd wind at Vuelta after seemingly hitting the wall.
Evans, Samu and Menchov should get some mention here, although Evans hasn't shown the ability/luck to make it through an entire grand tour without injurying himself in some way, thus making evaluating him difficult.
Samu is similar to Sastre in that he will get dropped at a certain point on a climb, and suddenly reappear passing those that put themselves into the red earlier in trying to ride beyond their abilities. The difference though is that Samu is rising while Sastre is in a steady spiraling decline. I'm quite curious to see what Sastre does in the Giro, where he plans on riding in support of Menchov. He's shown absolutely no form this season but then he's done the same in the past, except not to this degree of concern.
Menchov and Samu had a fine battle in last year's Tour with Samu gaining the edge in the mountains and Menchov pulling off a fine performance in the final ITT to snatch the podium spot. Menchov has shown to be quite resilent in the mountains, able to hold his own in all 3 grand tours, all with varying parcours. Year to year consistency hasn't been his hallmark and I think that is due in most part to questionable decisions in his race schedule.
I can't leave Nibali out due to his age, his rise last year in winning the Vuelta and making the podium at the Giro while riding in support of Basso. One of the areas, which I think is quite important, which I would have give Nibali the edge over Evans is in having the smarts to adapt and realize what works and what doesn't. The example of this is his altering his strategy in the Vuelta to answering the attacks of his opponents. Where earlier he tried to answer immediately and eventually blew up, he was smart enough to change in mid stream/mid Vuelta and slowly attempt to reel in his opponents which worked quite well for him.
