30m. It's great to see people are enjoying this climb but somehow they have got the description wrong in the 2016 guide, which is odd as it was fine in the 2000 edition; here is the correct route.
Step off the large boulder on the right of the buttress onto the blunt arete and follow parallel cracks in the rib to gain an easing and the almost horizontal juggy break that cuts across the crag. Traverse along this leftwards with difficulty and step down into the top of the scoop of Creeping Jesus. Pull out of this leftwards onto Fisher's Folly. Move up to the roof and traverse under it to its left end. Keep moving diagonally leftwards to finish at the top of MGC.
