It’s fairly simple as the title suggests as well myself providing some examples :
Hamilton : Bahrain (oddly), Monaco, Korea, Monza & Spain, maybe Suzuka as well.
Button : Spa, Singapore, Brazil, Monza, Australia
This applies for the 2012 season.
You know what i want from my articles; mixed opinions/suggestions, reasons justifying your choices and that’s pretty much it. Cheers!!!
