Me and a mate did leg 2 (c/w) on Friday with the clag down and plenty of snow on the ground. Were comfortably inside 23 hr schedule despite poor ground conditions. Coming off Dollywaggon was slow - you couldn;lt run down as it was so slippery.
Main discovery was the good line up Clough Head, which shaved 10 mins off the schedule. At the stile in the fence after the wet section there are two gullies running down up the fell (you can see them from the road). If you take the right one up, seemingly into the screes above, there is a grassy line all the way up. It's a little steeper than the left hand approach but its good ground, hardly any rocks and you pop out 200m from the summit. It's more direct and the steep section is very short lived and thus represents a saving worth making as it will not turn your legs into toast.
