Cool vid. Very sexy rings and that webbing, very light and strong. I think that adding two chairs to the hammock rig is going to add a little too much weight for me!
Wise move going to the climbing rings. Now you can sleep easier at night not worrying about if the welds on your steel rings will hold.
Add a slippery half hitch to the webbing after the rings for extra security.
Tried it all last night and all worked well.
Syb: The chairs actually fold up quite small and give me something to relax in around camp.
