I was just looking over Zpack's website and noticed that they have available carbon fiber tent poles of various lengths -- http://www.zpacks.com/accessories/tent_pole.shtml

Noticed the 32 inch pole comes in at nearly an ounce.
Has anyone ever used them or tried them? I'm intrigued by them and wonder how well a couple of them might work to raise up one side of a tarp, for example.
