I am lucky enough to race cars on the European circuits. The trouble with Grand Prix tracks is that they are all being mucked up by trying to accommodate F1. Silly chicanes put in to slow them down, create overtaking places (yeah right!) and suit TV camera's. But Silverstone can still be run as it should if the organisers select the "old" circuit for the meeting. Brands Hatch is great (allowing for the fact that they have reworked Dingle Dell (it is alot safer than the old car breaker). Spa is awesome but they couldn't resist changing the Bus stop chicane (just so long you don't get many laps to get it right). Hockenheim, Nurburgring (GP), Assen have good points but lack a bit of soul. Dijon is cool - not changed and has a huge straight up hill. See you tube for the 1979 F1 Renault v Ferrari for 3rd place - 2 laps of the best racing you will ever see!
For 2008 the circus will take us to Barcelona, Monza, Spa, Brands June etc etc - lucky boy eh? One small point - i never win as i am just not quick enough!
