This pitch is one route right of the not so classic Arsenal route "Dope Party". Squeal like a pig was not affected by the mass of rock that came crashing out of the bowels of the Arsenal a few years ago.
Climb up for five bolts to a good jug break. Psyche up for a very short boulder problem which gives you a bit of a pump before embarking on the big roof and the aptly named squeal move. A long draw under the roof will help run the rope a bit more smoothly once above. Thug your way up and over the roof and clip two more bolts en route to a wee bit spicy run to the anchors. I figure if you blow it looking at the chains your going for forty.
