Make it extremely technical. Elevation gains, decreasing radius and negative camber turns help test the fine skills of any racer. Id make it a good mish-mash of fast to slow progressions. Race City is a decent course, but its so very flat I find it horrendously boring, that and the front straight is way too long for any track. (obviously it serves the purpose of a 1/4 mile track but...)
I really like Laguna Seca myself.
I think that would make a decent focal point to take notes from.
