In my mind, there are the absolutely world-class,  ‘Big 6’ V13s of Joe’s Valley. Masterpiece, Last Great One, Blackout, Mask of God, Black Lung, and Slasher. I think Slasher may be the most difficult and most quality, depending on who you ask. It certainly has the most famous sequence and the hardest moves.

Pull on from a positive hold with horrid feet. Move to the ‘slasher’ hold; possibly the areas most famous. Make a heinous span to a nice sidepull, then execute the final dyno to the lip.

Three moves of insane difficulty. A true finger testpiece. Maybe not as famous as Black Lung, but certainly more pure.
