Uber Classic. This problem was recently up-rated on a popular consensus from it's original rating of V6. No matter what it is, this problem is sweet. Start SDS on a sloping rail with a toe hook and press with your feet. Make a big move up to the slope on the lip and match (crux). Top out up and right. The stand start from the sloper at the lip goes at V4.
Walk around the corner (away from the cave) from Kung Fu Grip. Same start as Mortal Kombat.
