20" pad plus underquilt-type sides?
Be gentle with me -- I have almost no hammock experience. I know you hanging types prefer wider pads - the reasons I've heard mentioned are stability and need for more insulation on the sides.
Would it be posible to use a 20" x 72" pad and insulate the area about 8" on either side of the pad with down or synthetic insulation? I ask because we dinos have a pair of Ridgerest left over from the days before the female dino got mangled.
