GV East would be too small and too fiddly. The full GV would provide that long corner in the tunnel showing off a car's handling at medium speeds, and would give the hairpin and and the chicane testing traction out of corners.
I was actually thinking Fuji or GV. But I went with Fuji because it has a longer straight, so when we're not racing, we could drag race down the 1km long straight to truely compare differences in top speeds between the cars. But both Fuji and GV have slow, medium and high speed corners. 👍
