On arriving at the crag Hamish worked the route for an afternoon then returned the next day and dispatched it on his fourth redpoint attempt of the day. A remarkably quick ascent!

Hamish used a new toehook method for the start, and suggested 8B+/V14 may be more appropriate for that method. He was also extremely close to flashing the problem, only making a minor dab on the last move. [2] References |
