Merlin The Happy Pig

As for Basil Brush, start on the brown wall in the centre under a bolt. Move right-wards up past the second bolt (crux) and clip the 2nd bolt on Pigs Can Fly. Finish in the crack. Now has a more in line third bolt and a 2 chain anchor. Has been straightened out, with an extra bolt at the top and added the chains. It is a touch harder than 19, about 21 seems to be the consensus.
