Aston National Reversed. A very seldomly driven track that offers a nice change and interesting overtaking opportunities.
I'd agree to both Aston National proposals with about all cars: FZ5/RAC, XFR/UFR, FOX, FXR/XRR. In order of personal preference: FZ5/RAC, XRR/FXR, XFR/UFR, FOX.
I don't like National. it's far too open for my tastes, how about KY_nat @XRT+RB4 or something, or even FOX, Just give me a month or so to learn it, My new job's a night shift so my practice time is limited
