Pole possition is good if the compromise is well calculated. The tyre wear on this track is poor, so starting 8th or 9th behind a lot of dirty air will exacerbate the problem.
Vettel should be able to run away in clean air if his start is good and if the quali setup can complement the added weight.
He also will have control of the pace of the race and have a clearer choice on when to come in. However i don't think things are going to be so smooth for redbull.
He seems to make errors running heavy, so we have to wait and see if he can manage guys at the front like Alonso, Massa, Hamilton on the first lap.
With that i don't think a team doesn't want pole. They will take it if the setup works for the added weight.
One question i have though is, when does the weight reduce to a level where the car no longer feels heavy and boat like?
3/4 tank half tank?
The drivers are going to want to push harder when the weight is down to some level. Or do they push hard when the tyre life is at it's end and a pit stop is within 2 laps?
