We like to encourage webbing for tree-hugger use, no matter what kind of suspension. It's arguably better for the trees, and certainly better for 'perception' of hammockers. So I'd recommend just using a full webbing suspension to keep it simple.
Polyester webbing and old style cinch buckles
are cheap, easy to get, and work very well. That setup is so simple that almost anyone 'gets it' after seeing it the first time.
