Thanks. Sounds like he could have done it on his second day:
Well into the session, precisely one minute before sundown I managed to catch a nice breeze and found myself at the mantle! However I looked down and my spotters were nowhere to be found. With no one spotting, it was unsafe to do the last move and I had to drop down. I was gutted having just climbed a really hard, highly friction dependent climb. And I never made it back to the top again that day.
