I'm not fond of the start finish straight to be honest. It's great for the start and finish but not very good inbetween - it's just a straight.
If you go for platinum tickets you'll be fine. We've done many over the years including Luffield, Village and last year did Club. We are in Club again this year on the far left as you look at the track. This allows you to see the pits, start/Finnish straight and it's a fast corner. You do have to get a three day ticket for there though.
