Go into the little "room" formed by the boulders. With Nami in front of you turn left to the boulder that forms the back of the room. Start low on a big notch in the rock with obvious good feet on the bottom. Dyno to big slopey lip, once over the lip sink a hand into the giant horizontal crack and top out.
I used a large left foot to rock up and mantle with my right arm while using a good left crimp to stabalize myself. My friend and i posulate that it might be a V1 if you match on the big sloper and use a heel hook to roll over the mantle.
