Not to sound the ignorant American stereotype here, but, my local track is VERY underrated, VERY technical, pretty much The U.S.'s Bathurst.
Road America, it's a 4 mile road course winding through the hills of Wisonsin, All the way from a strait that can top a Hyabusa out, to a curve called the carousel that will make you wonder if your going to ever stop turning.
The uphill corners, the downhill corners, blind crests, off camber's, massive and light elavation changes, light sweepers, flat out kinks, and its rather wide for being as long as it is.
Plenty of passing room, but narrow enough to close the door on a rival trying to make a last minute move. Totally under rated, never even considered unless your from out in the sticks like me and have access to it.
MCN topped out 180+mph in 5th gear on the new hyabusa at road america on the front strait.
I would think that if they were going to put in a track that was interesting and competative, Cadwell(?) Park, Bathurst, or, R. A. would be on the top of my list to see in it.
