you'd rather switch than fight
(sorry, the title is a reference to a cigarette ad...maybe you had to be there...)
So Mule, what motivates the move away from Claytor? Is it anything other than not being able to get something "just right" under your head?
Something to consider here...for my bridge hammock I sewed up something really simple for back and head support. The idea is to be able to recline in partially upright position to read. But it turns out to be good also at raising my head slightly when I'm more fully stretched out.
It consists simply of a piece of 1.1 oz fabric 3.5 or 4 feet long and 34" wide, hemmed, with a strip of 1/2 webbing sewn at one end. The webbing has loops, which makes it easy to clip the webbing ends to the hammock's rings.
The fabric stretches down into the hammock body, where I'm sitting on it (for reading) or laying on it (for head support). The tension between its connection to the rings and my body weight is making the back rest.
This just might scratch where you itch. It would take you all of an afternoon to make a bridge hammock and find out. And/or we can get a hang going in Feb. or March and you can try mine out.
