I think the Brawn cars will do well, both cars up front mean it's not a fluke or just down to a driver who can pull out a good lap.
Hamilton is a charger. It cost him the title in his first season but where he is this weekend it'll do him good. Expect to see him finish a lot higher than he starts.
Yes, it should be an interesting season, although the cars do look stupid with that snow plough on the front! But F1 is increasingly becoming an irrelevance, just another way for people with money to w*** off! The way the rules are going it won't be long until there are road cars that are faster and more technologically advanced.
