In reply to David Gainor:
The hidden jug is there, and is very good. If we told you where it is there would be no joy for you when you find it! Billy Pigg plays to the strengths of old Swanage climbers, lots of upper body strength, useless footwork (so we don't get confused), and not much imagination.
Find the hidden jug, cut loose, get a foot jam, yard up to the even bigger jug and it is all over. If you think that the lovely, solid corner of the second pitch is "loose" then the Ruckle has many more surprises waiting for you.
The guide book description is spot on, it is a great introduction to roof thuggery and the steeper Swanage routes.
