Sounds like you were having a bad day Kieran. When I wrote up my variant finish I did think about putting in some sort of a note about that fourth pitch [your 3rd]. It is much shorter than the description – possibly only 10m. I initially got lost trying to continue up the wall above the crack but eventually decided that it didn’t go that way. I belayed just to the left of the ledge where you had the sling. From there an obvious 6m juggy traverse line leads across to the foot of the chimney. So ‘veer left’ actually means step left on this occasion. In the photo I reckon it goes straight left under the overlap from where you have the line going up diagonally left to your high point.
