If somebody needs to attack in this situation, it's Andy. He has to attack on Galibier, because then, I really don't know where he hopes to gain at least 1 minute on Evans and probably on Voeckler too. And I don't really think, he can gain all of time he needs on Alpe d'Huez (and then there would be the same situation as on Galibier..). And it's needed to say - there is really low chance he will gain some decent time on others if he still will look for Frank and for Contador too - he can't look all the time for him, because there are some presumptions, that he will be his threat once again, he really isn't his biggest threat in this moment.. If he wants to win this Tour, he needs to gain some serious time and that he won't do without some proper attack as he did on Port de Bales before he dropped his chain off and do this without looking behind him, even if his brother isn't as good or better than him, otherwise he really can't win this. He seriously needs to do an ALL IN attack, but way earlier than in the last 200 meters of this stage like today.. He is probably the best climber here, but with bad tactics he will fail like Cancellara and Schlecks in this year's classics..
But in the end I will be happy (more or less) if this Tour will win anybody from Top 8, except of Evans and Contador..
