I did this one with Charles starting out in tennis shoes which I took off for greater friction. We didn't have a rope, but downclimbing was fairly easy.
The standard way described for the pinnacle is to climb up to a notch along the NEside then up the short face to the top. It is possible to make the climb longer and more interesting by starting down and right at the base of the north end. That being said it would be hard to justify the long bushwack for this climb alone, but to combine with Nun Buttress or others would.
