Not quite the perfect photo, but unequivocal 5 for the hugging/grinding the route posture. Not leaving a runner on top of the arete will no doubt have encouraged your second to avoid falling off!

Haha thanks, your comment alert took me on a trip down memory lane. Honestly, if there had been a worthwhile runner anywhere near the second, I'd have placed it! Leader fall from where Dan is would have at least removed my legs... A remarkable pitch.
