Alex Honnold's Welsh slate climbing experience

Opis:
While on his 'Flying Solo' tour, we took Alex Honnold to the Welsh slate quarries with pro-climber Hazel Findlay and legend Johnny Dawes.

As Alex says about slate climbing, 'For the real connoisseur of world climbing I feel like it's a must-visit'. But which route do you think he found to be like 'normal' Yosemite climbing?
