Heidfeld or De la Rosa were LRGP best choices, and I think they've made no mistake. Heidfeld is very skillful, he is a perfect "teacher" for Petrov, and I think Kubica will cheer up if he's his substitute. After all, they were good friends at BMW.
@Loque I'm sure Lotus (the Malaysian one) will score some points this year. At least ten points, that's for sure. They've improved in all areas, and as you said, Trulli is an excellent driver. He deserves much more than just Monaco 2004. And Kovalainen is not bad, but he could have done much better in McLaren, at least in 2008. Just one win due to Massa's engine failure is not significant, unlike Trulli, who did an excellent race from PP in Monaco 04.
