As you have visted this thought before, how long do you think the bury needs to be.
The more I read about this, the less convinced of my own idea I become. In theory it should work, however, the slippage and length of the bury could limit its uses below that of my current set up. As I'm not a weight weenie, I think I may just keep with my current set up as rigging the suspension line takes no time at all. Might remove my Karabiners though and just marlin spike a couple pieces of trail debris in place to hang my hammock off of.
