I agree, I think Lance will win #6 but he will have a fight on his hands.
1) Armstrong
2) Ullrich
3) Hamilton
4) Mayo
I'm tipping Mayo to take the alp d'huez time trial but have you notice sometimes when pure climbers tip their hats to be "men of all seasons" they sometimes loose that zip on the climbs that makes them brilliant climbers. I hope this isn't the case with Mayo!
