Adam Ondra made the second ascent of Christian Core's Gioia yesterday, confirming that it felt like a V16 boulder problem. In an interview with planetmountain.com, Ondra says: "Every single move is at the very limit and so I do think it's V16. I'd compare it in difficulty to Terranova [V16]. If you were to give this V15, then the bouldering grades wouldn't make much sense anymore. You'd have to downgrade all the V14 and most of the V15s as well. When Christian sent the problem he thought it could be V16, but he first suggested V15 to play things safe. I can only congratulate him for this superb ascent three years ago."
