I really, really liked Fahrenheit, especially after it had warmed up and we got an excellent night ride on it. The drop's insane, the N-Loop is as well, the Corkscrews are great for being Corkscrews, and the finale turns/hill run like a blitz.
However, Maverick has a lot more to it, but looks quite painful and the inversions aren't as interesting as Fahrenheit's. So, I dunno, I'm not voting - but I did really rate Fahrenheit highly.
