Paul Robinson has done the second ascent of Dave Graham's Psychedelic, at the Gorilla cliffs outside St George, Utah. Dave did the FA back in November of 2001, giving it 9a, but, at the same time saying it's very difficult to grade.
In an interview with Mountains and water, Paul says "It is long moves on small holds up a slightly overhung wall. It is 60 feet and can be summed up as a v6 boulder to a v13 boulder to about 30 feet of 13a to the top."
The Climbingnarc has a video showing Dave making the FA. I must say it looks absolutely heinous!
