Thanks Tinkker and Shug, that's the info I needed. It is appreciated, but I am going to pass on the Draumr and stick with my Exped. I just don't want to be dependant on a air mattress to make a hammock useable. I have been comfortable in my set up for a few years, but having more head/foot and elbow room sure would be nice and it is tempting.

I am going to steal the 3/8 th Pex idea for the hoops on the Exped.....I hope they will fit in the sleeves.
