Really? I like sector 2 best, I don't mind sector 1. Sector 3 is too awkward, there is only really one good line through that section, so you can't really fight for positions and the line is too stop-start, you build up speed then have to slow and turn tightly constantly. The braking points for each corner are in the middle of the previous corner and the general racing line is quite scruffy.
Sector 3 is where everyone online makes mistakes though, its very easy to get a little ambitious with the speed you take each corner, especially when you are trying to catch the guy in front, so consequently everyone seems to always spin or crash in this bit.
Sector 2 on the other hand allows great battling with swapping places and allows a little bit of deviation of racing line and braking points. Taking turns 7/8 flat is a great feeling when you nail it.
As a whole, I don't mind the track, not really one of my favourites, sector 1 is just there to outbrake the AI and sector 3 is too awkward. I find it quite difficult to put together a really spot on qualifying lap but I find it very easy to settle into a race pace, purely because trying to find some extra time in sector 3 is incredibly difficult but simply driving within your limits is easy. Its not really the line you take its more the speed you take.
Also, because it comes straight after Suzuka, I can only ever fall into the trap of comparing the two....Suzuka is a dream to drive in comparison.
