I'll be there Sunday, Forget Corams, new run off area means you are so far from the track. Russells chicane is an excellent vantage point especially with a 200 - 300mm lens, Riches can be good for bikes cranked over and the exit of the esses is excellent for action shots.
All of the bike images were taken at Snetterton:
