Varsha is amazing... he really is very knowledgeable and rarely stumbles or messes up. Tommy Schlongkendall can really get him flustered, though.
And Matchett... that guy's a walking F1 encyclopedia.
David - did you actually watch Priestly work the pits at the USGP? He was a complete idiot. I think he should stick to the celebrity races. Anyway, I think his IRL Crapwagon crash kind of put an end to his racing days.. at least I hope it did.
