Nothing special, just another of many slab routes on this face. Run out, but I would not hesitate in soloing the whole route. On the soft side of 5.8. Pinky Lee (5.10d) is a must do further down. I led Pinky Lee but will never attempt Hot Knife (5.10a)....looks like a ankle buster to me....such is the diversity of Jtree.
I climbed Helix and WAC many years ago, when I was first learning to climb. My calves just ached after climibng WAC.
