A quote from Hermann Tilke
http://www.autosport.com/news/report.php/id/87544"The only problem it [the new surface] will cause – and to me that is not actually a problem – is in terms of grip," explained Tilke. "A lack of grip should not be a problem because we have the best drivers in the world here. Plus, it will be the same conditions for everybody. There will not a problem that the track will break-up.
"I think on Friday the track surface will be very, very slippery because it is brand new. That means you will probably see some spinning. And, it will not be easy to find the set-up for Saturday and Sunday because the track will change a lot.
"That means some drivers will make the wrong set-up choice, because you are going to have to second guess what is the right way to go."
