I climbed up this lay-backing off the crack, which made it quite a bit harder than it's 5.6 rating would suggest. My climbing companion hand-jammed up the crack the whole way, making it look easy. I've got to figure out how to do that.
I've heard people refer to this as "the Hardest 5.6 in the World", because it's very awkward for novices/amatures, but for those who've done fat jams like this will love it. It's a fun, fast climb you can really play around with.
