Thanks Arc. Got frustrated with Suzuka so decided to try my hand at Monza and got gold in a couple hours. Not as bad as I thought it would be. The hardest part is learning the timing to cut the second chicane.
BTW, a piece of advice for anyone thinking about going for this plat (and already has the 2 online trophies). Don't think that a wheel is suddenly going to make it easy. Even with a wheel the Vettel challenges are almost in a league of their own IMO. By comparison Beat Zico and Zone Zues seem comparatively easy.
:edit: Vettel challenges complete! Merry Christmas to me. I can't really describe what I'm feeling right now.
