Here are my thoughts from laying in it for a few minutes.
-It is really comfortable.
-I did not feel any torque on my waist when I laid on my side or stomach.
-You need a pillow. Not a big deal just something to figure in. I use one anyways.
-I would need somthing underneath my knees or between them on my back or side. Again, I use one anyways in a hammock and in a bed.
-I need a long model. When you are figuring the length, remember when sleeping on your stomach that your feet will add a few mintues of length. Probibly on the order of 6" to 1'.
-I would made the head end high enough to be able to sit up in it and use it as a back rest without having my head in the netting.
-I would use hiking poles as spreader bars. I slept in the backyard in my hammock last night and was thinking about it. I would rig something up where one side would attach to the handle side and the other to the end of the first section in the hiking pole. This would put all of the force on a continous metal section and not on 2 or more sections.
-I would use spectra to go into the rings then straps to the trees just like my normal hammock. This would also save some weight.
-I think 1.9 untreated would work just fine and save weight over the material they use.
-I would make mine a little wider. When I laid on my side my knees would hit the sides. This width is kind of determined by the length of the spreader bar.
In the end I like the design. I am planning on making one when I get back this winter. I want to make it also since I think it would work on the ground really easily. I would use an inflatable pad, probibly a DAM as bottom insulation in the air and padding on the ground. I think it would be the perfect hammock for the times when you do not know if you can hang or not, but still need bug protection.
Is that too much to ask? Girls with frikkin' lasers on their heads?
