Yeah it'll be really interesting to see the transistion to 3 tiers. In theory it should mean each Tier is even more competitive and as you said where the new drivers stack up will be really interesting!
I am very nervous. I haven't practiced a lot and when I compare my pace with some of the others in my tier, I am a lot of the pace. I do feel however that I can show that I can do consistent laps better than the rest.
