I love to paddle also. I'm planning a long river trip for this summer. I have been using a 1/2 person mar tent for kayaking and motorcycle trips, until this summer.
I now have a few hammocks, Lawson (probably to small for you),, which is designed to go to ground. A Dangerbird will soon be on order.
You make good points. My wife will be along for the 1st week & she will have the MSR. I'm sold on sleeping in a hammock, but in my Colorado River, Lake Powell, Mead, Mojave, Havasu, trees r few and far between.
