If Hamilton can't pull a pole+win out of the hat in Canada.... I'm selling my Hamilton WDC betting slip
It will be interesting to see how the Ferrari performs in a traction + top speed circuit. It's been their weaker point over the season start, it seems.
The Lotus people apparently have a theory that it's the smooth asphalt in Monaco that caused their severe rear tyre destruction (as opposed to degradation) - and if that were true, then good luck for the race to Lotus.
I think actually the prime pole contender would be Schumacher, followed closely by Rosberg. Their super-DRS could see them in very good stead.
Red Bull I suspect will be great in Sectors 1 and 2, before losing out over Sector 3. Last year the DRS advantage was more than enough to offset the Red Bull's straightline disadvantage and help it overtake. It will be interesting to see whether or not that is the case this year, with the shorter zone.
