Try Hungary it's a super fast track that is really fun one you get a rhythm going. Especially turn 8 flat out! WOW!
Melbourne is fun too, there are a couple corners you can do flat out that are fun. Turn 1 is challenging - if you brake just at the right time you can make a few 10ths.
The only track I really hate so far is Shanghai
Anyway I put this game on the backburner, I am trying to rehab my wrist and steering hurts it. I hope they'll have the bugs fixed when I can play again
