I was there in 2004 then this is my third year back 2015-2017. All kinds of different pavement but it looks worse than it really is. Was pretty green in the mornings (only got to mid 70s/low 80s) but good later. The only place I'm really aware of the runoff is in T4 which is the fast right hander after the off-camber left. Get that wrong and you could be launching off the track but otherwise I feel pretty safe there.
There is a grey blur, and a green blur. I try to stay on the grey one. -Joey Dunlop
