This problem is on the magoo closest to the access road it is on the left hand side while facing the rock from the road. It is route 1 on my pretty little picture.
Starting in the small cave go for the pocket to your left. Getting your feet high and work your right hand up the arete until you hit the sweet spot (you will know it when you hit it) and top out. If you want to make it a little easier you can use something other than the arete to your left but it seriously simplifies the problem
