Zander Waller

Prior to this ascent Zander's hardest boulder was an 8B! However he did find some new beta which he suggested made it closer to 8C.

The new beta changes the crux sequence of the boulder from V14 or 15 into hard V13. This makes the breakdown of the climb V13 into V11.

As for the sit, it's really hard! I got so shutdown trying the moves on it yesterday. It's definitely harder the taller you are, so anyone who is tall enough to do the new beta will really struggle on the start, and vice versa. [2]
