@andae23, I’m not sure about GP2 tyre allocation (too lazy to look it up – shame on me!), but I think Van der Garde didn’t have any primes left. In the feature race he ran prime – prime (changing only the rears), so he only had raced rear primes left.
I don’t know about the rest of you, but I really dislike this reversed-grid rule they have. On Saturday, Gutierrez lucks into an eighth place after a poor race (well, a poor second stint anyway), and he is awarded with the chance to win a race. I’m surprised people in P6 or P7 don’t start pulling over in order to get pole for Sunday, especially at tracks like Monte Carlo or Hungaroring. For the points total, there is not much difference, and adding a win to your tally is much more important than finishing sixth (e.g. on Autosport “Esteban Gutierrez sealed his third GP2 win of the season”).
