turns 1 to 10 is all redbull. I think their car has the best traction exiting slow corners. They should be able to hold off the Mclarens through half of the track.
Mclaren only have the rest of the track as an advantage. I am not sure how much of the f duct can be used in the little 7-8 straight and the 9 to 10. They are going to need to turn it off to use all the downforce for braking.
One thing i am interested in is the chicane.

Wonder how Vettel fares through it. There is speculation that chicanes aren't his strong point. Guess we have to wait and see.
The HRT looks like the #1 candidate to scrub the wall of champions as well.
