Here's a video of my attempts and send of Black Lung in Joe's Valley. This is really a great problem, hopefully the video does it justice and gets some psych to everyone.
I forgot to mention it, but La Sportiva has a little article that I wrote about my trip to Joe's on their LIVE website. Check it out at this site under the "Crown Jewel" section:
