It is, but its about bums on seats as well and Lynn isn't quite as close to Heathrow as Reading.
Reading staged some great WTC rounds in the past. Like Poole, Swindon and a well prepaired Oxford track it is fair, no weird shapes and if Ole Olsen does the track it dosn't matter where it is it will have as much grip on it as my head! but again its close to Heathrow, and with the Mad Stad carpark next door parking will be easy for everyone.
