Route topo for "Here comes the Sun". This route has also been free climbed by Leo Houlding et al - the E6 crux is probably the A3 pitch as this was the most precarious section with thin gear.
Now it has been cleaned and repeated, it should be possible to freeclimb nearly all of it at about E4. 80% of it was free when we did it anyway. Go and enjoy - the climbing and situations are superb.
