From memory here is how I do it... although I haven't been on it in a while:
- So starting from the big pocket out left just before the roof. Step up on the 'peanut' hold on the point of the arête and go to the big jug in the horizontal break at the base of the roof.
- clip the bolt here and rest (I think this is the last bolt before anchor?), don't forget to breath.
- From here you follow a series of juggy sidepulls which face left (away from Witch). It should be pretty straight forward if you stand up on your feet and concentrate on turning your hips out, so as to do a sort of layback off the side pulls. For me it's only 2-3 moves to get to the next big jug under the anchors (although I'm pretty tall).
Hope that helps, although I'm sure other will give a better account
