That's as far as I can remember.
Personally, I think Vettel had mastered the donut with perfect circles using half-throttle. That's the perfectionist mentality of Vettel. Gotta respect that! DC's donuts are pretty good too.. but I'm sure he had more practise than anyone else.
But my favourite has to be Webber's d!ck! which isn't really a donut... Hmmm... LOL
