Kind of depends on what happens with the layout/pits for this year. Normally I'd go for Woodcote, as far round towards the pit straight as you can get. This would give you views of Priory, Brooklands, Luffield, Woodcote, the Start and pit entry at pretty close quarters, the finish line and the entry to Copse at a distance and a big screen, can't really ask for more. If they are using the proposed new layout you'll lose Priory but will be able to get the cars heading directly towards you down the national straight. If they move the pits/start finsh for this year (which would be ambitious - I'm guessing that's planned for future years) then this spot would obviously lose a lot of it's appeal.
