On my recent Smokies trip another backpacker had a Eno tricked out as was posted in another topic. My son found a web site where these riggings could be checked out and bought. Maybe some of you wouldlike this info.I have not tried this light weight system personally. I can tell you I was impressed with what I saw in the field. The guy that had this system ranted and raved about it? Here is a link if any fellow Hammock users are interested.

The figurenines are really cool! Figure nines are available at backcountry as well.
