The sun shone as I ate, and, galvanised by a phone call to Jones I decided to head out again to see if the holds had dried. They had! And the sequence worked! Dreamy. Here's a pic of the line, its a sit start from the smaller stones on the ground, then out to the small chalked prow and finishing with a mantle onto the boss/nose.
Here are a few pics from the last few weeks:
