Very different from the routes to the right, this climb is entirely defined by 3 hard moves, about V4, with very casual climbing before and after. You can spy out the moves to some extent from the ground, staying left with an undercling, or right with a sidepull/undercling.
The top has a missing hanger so it's a tad run out on easy climbing. Watch where you allow the rope to go - it could be easy to tangle it up in the tufas if you don't pay attention.
