Just curious:
If Rouen, which is some peoples' fave track is "dull" what tracks would be interesting?.
I like to know these things so I can plan future events.
I think Rouen could be satisfying while fighting for position but, other than the leadup to the hairpin, it's a series of long straight>turn>long straight combinations that don't add up to a satisfying rhythm for me. That same overall feel is why Road America is my least favorite of the popular american tracks. On the other hand, I like the old Sebring, Daytona, and Silverstone layouts that are similarly laid out except that they string together some good sets of turns and tend to carry more speed through their self-contained corners.
For the overpowered gripless GTs used in these rounds, I think Kyalami and Spa were good choices that I wish I could have run. Otherwise, I think Riverside, old Road Atlanta, Mid Ohio, Oulton, and the tracks EvilClive mentioned are satisfying for anything with more power than grip.
