There is no beta for this boulder on this site. The guidebook says there is a 13? to the left of what you are doing. Where did you start and how do you finish pictured line?
I've climbed the line from the far right (if looking at the boulder), traversing in from a sit. I've also climbed it from a sit slightly left of the main line, where you do a small dyno and then climb the main line. It tops out via the main line/seam and then going left (still fairly dirty).
