Voeckler won 2 stages last year/ took the KOM Jersey. That performance along with his 4th place in the 2011 TDF makes me feel as if he is a better climber for the moment.
TJVG only finished in the top 8 of 1 TDF climb this year. http://www.cqranking.com/men/asp/gen/race.asp?raceid=21641
Sure that could be construed as him having good endurance but the GC by that stage was practically settled. Out of those contenders Wiggins and Nibali will be doing the Giro but Wiggis will probably be back at the TDF and Evans who i still think will go well, even though i do have some doubts, Anton- who will hopefully go well on at least one climb, Andy who will probably be fine by the TDF, JROD and of course Contador. The mountain stages will also be harder this year/ hopefully not tempo ridden. Quintana will be there, maybe Gesink, Hesjedal, Mollema, Cobo... Also i think Talansky will go quite well and i hope Taaramae can.
I like TJVG but the memory of him blowing up so completely at the ToC http://www.cqranking.com/men/asp/gen/race.asp?raceid=22499
and at http://www.cqranking.com/men/asp/gen/race.asp?raceid=21255
when he had such a big race lead of 38 or so secondshttp://www.cqranking.com/men/asp/gen/race.asp?raceid=21250
I definitely do think TJVG could win the TDF someday though/ like him.
