last bit defo the hill above that road, and the angle of the hill is about right. ( sir william hill rd is the road that goes straight up that hill about 2 miles towards calver.
these boys are very quick, there's footage of them doing all the legal, and some not, lines in blakka recently. very impressive ( it's linked on moredirt.com forum)
I'm not surprised that Hill has been dug - looks like it's been used for a few seasons. IIRC the lad that made the film has just come back from a very extended tour of boarding and riding in the alps - he's certainly on it.
