Siren's Slab v4

Start right of the arete on two good right facing edges. Reach right to a series of holds to set a high left foot, then figure out how to work your hands up high and left to the victory crimp. Easier moves from here take you directly up to top out. Difficulty is a bit contrived. Easiest version fully using the arete could be V2 and the strictest version with no hands on the arete about V4.
