Monza for me.
Flat out,Brake, Chicane. Flat out,Brake, Chicane. Flat out,Brake, Chicane, Paraboloica then repeat.
I'm exactly the same I like Valencia but I'm not the fastest there. Spa, Istanbul and Catalunya are a few of my favourite tracks. I also enjoy the medium to high speed corners. Istanbul has a good mixture of all I think corner just before the pits is one of my favourite corners but I find the breaking points very easy to find on this track as there are a lot of visual markers. I'd say Istanbul is one of the best tracks for practicing a variety of corners but then again Canada is pretty good too with easy visual markers and a good selection of corners.Its funny with Valencia and me. I enjoy the track but am not very competitive there.
I think I'm probably the opposite of Andrew above. I seem to like and be faster on tracks with some medium to high speed "steady state throttle " corners: Spa, Turkey, Catalunya. It must mean I have improvements to find in braking for the stop start "point and shoot" tracks.
