Volker,
I've used a couple of your setups before and found them very good, though I do prefer to make my own, I got a long way to go to get your understanding
Anyway, I've taken your Las Vegas and changed it to work with Rockingham UK. As it's your original set, I thought I'd better give it back to you as it was your great work that got me a good set for my forthcoming race. Thanks very much for the great work and sharing of your hard work and knowledge
