Paffet will end up at Pro-Drive if he's going anywhere. I deeply hope Nico ends up in a decent car soon and Heikki needs a chance to lead a team, i think he needs a confidence boost after what Renault and McLaren have done to him
what have McLaren and Renault done to him? 
I think Kov would be the first one to admit there is no excuses for his career thus far! its had its ups and downs but no one has held him back what so ever. unless youre a conspiracy theorist where Lewis can only beat his team mates in Fernando and Heikki by having team orders his way. 
Lewis is rightly the number 1 driver at McLaren, let's just establish that to start with.
My grievances with Renault is that they gave Heikki an uncompetitive car and then criticised him publicly after just one race. He is evidently a confidence driver and Renault made it their business to undermine him the whole way through 2007, even when he was responsible for their only stand-out performances in that season. The compare that to Piquet's treatment, he has been nothing but rubbish and it took them until past the halfway point of last season before they started publicly criticising him.
As for McLaren, the damage was already done to Heikki's confidence at Renault but operating a blatant 1 and 2 driver policy on race day while saying to the press that it is not so is extremely damaging to a driver's confidence. Putting Heikki on a set of tires purely to see if they would work for Hamilton and then claiming he has equal treatment is just not on.
Heikki's form in previous series suggested that he would be a potential top 4 driver in F1 but it hasn't worked out that way. PArtly down to him i think but the impact his teams have had can't be ignored
