There is some information at the following link on hammocks.

I still use a tarp setup like the one pictured at the link.  The large tarp provides a place to keep all my gear dry and that is my only tarp on solo trips.  When it is raining I will cook and eat under that tarp.  I now have a Black Bird hammock and I prefer it.  The Hennessy and the Black Bird lay about the same. The Clark is a different type of hammock and it lays differently than the other two.  
Is there some place at copis that we could have a hammock test area? Jimbo why don’t you give a talk at copis and ask manufactures to send you hammocks for people to test.  I think you would be good at that.
For hanging my hammock now I use “Dutch Clips”.  You can find them about ½ way down this page.
