The Japanese boulderer Toshi Takeuchi reports the first ascent of Kuzan and suggests 8c as a rating.
His comment on the successful ascent:
"Finally. Today the dynamo succeeded. I climbed the extension of Borsalino. The new line includes seven 8b + trains and one 8b train, the Dynamo. I am very proud that I was able to give the classic Borsalino an extension. " In further comments, Toshi leaves it open as to whether or not it could even be a 8c +.
