On Southwest face of Carrier Boulder, there is a larger sidepull with a lot of chalk on it. This is the crux hold of this problem.
Sit-start low on next to nothing--right hand on a decent one pad, three finger pocket in the right hand, left hand will be on a miniscule crimper. Work out the feet on your own, I guess. I've seen and heard different beta for the feet. Pull and throw to the underclingy sidepull with the left hand, and move with the right hand up to the juggy pocket.
You know, I repeated this not long ago, and it's probably not V5... It might be V3? Fun line, regardless of what grade it is... Greg might know the name; I thought it was something like "Thelonious (Direct)" or something...
I racked my brain trying to remember the name of this problem after I saw your post... no luck. I thought "Thelonious" was on the front side of that boulder, but I could be wrong. For some reason, none of the names at the Maze seemed to stick with me. It's not very characteristic of me, I know. I agree with Dan, it's probably V3ish. Hard first move though.
