Tough choice
but Montreal is my favourite, mainly because i consider my self pretty good under brakes, and the long long striaght with challenging chicances
Spa comes second, as all the corners are fun.
Alex witch corner is Pouhon? is it that fast left hander where u just have to slow only a little? where Kimmi got all loose during the race there last year?
Monaco is a great, fun challenge, but push to hard and i normally loose a wheel
thats my top 3, i could go on and on but this post is big enough already!
