Interesting! I've not chosen curtains with him either, for the record, but have been out in the 360 a couple of times :-)
Regarding Rockingham, I had a real problem with fuel starvation going into hairpin 1 on the International circuit. I had 9 litres in the car and every time I took the corner I would end up stalling on the next corner... very annoying. Luckily I never had the marshalls out to rescue me :-)
So how do you know Jools then?
Sounds like we need to run at 1/2 tank minimum then.
