Glen Helen if you can get up on the bank. If not walk back 100 yards to the entrance to the bridge there as the riders nip in past the wall and your litterally a couple of meters away, if that. Im unsure of names of places, but if you go round the left at the top of Cronk-y-voddy, then the right, then the next set of two bends looks to be good.

Quarry Bends is awesome just for the sheer thought that one misplaced stone and you could be taken out before you could even react (not a funny thought the crashing but the sheer speed and danger makes for a thrilling day)

Gingerhall is a nice left hand bend to watch them getting on the power again, and the pub isnt 'alf bad either (and they sell Stella!).
