Start left hand in the pocket and right hand on a low crimp and make a big move. Trend left through crimps to gain the arete. Bust another big move and top out to the right of the arete.
This beta felt V7/8 (7A+/7B) to me. Bit cheesey and very gym styled to climb it this way but hey, same starting holds were used and bouldering is about finding the most efficient beta to get up anyway 😛
