If I'm honest, the reason I've not put my name down is because I'm not a huge fan of session days, and to have a session full of cars with massively mixed experience kind of takes the point away from doing sessions in the first place.
If I read it wrong and actually it's an exclusive sessioned event then I apologise and I'm in, but if it's just an exclusive session at an event with other cars then I'm not convinced there's any point. We'd be better off just picking an open pit day and all signing up to that (like, say, Bedford on Aug 23rd).
