The original route starts near the right edge of the sail, angles left to reach a wide groove, that leans right, then traverses left at the end. An exercise in rope-drag managment, although a direct 5.7 r-ish start can help avoid the problem. Must do!
I followed this route a few months ago, and it was sweet. the leftward traverse at the beginning is kind of hard to protect without smaller aliens or C3 or equivalent, although you probably could get some bomber small stoppers in if you are a passive-master. definately worth doing this guy, and the view is amazing. stays interesting to the end. I think we had a 60m rope and were able to rap off the top just fine.
