Chalked line a mere E6ish thing I think, must go back and finish it.
But the blank arete to the right, climbed on the left hand side, look very hard indeed. Slightly 'worse than square cut', vertical, perfect hard quarried grit, with no edges to hold the barndoor and not much in the way of smears for the feet either. There is a hold to aim for at the top. With the rocky landing jigged about a bit, and a pile of pads it wouldn't be death but very high. E9 7a/b if possible? If only I could remember where it was...
