i have replaced the stock HH suspension w/ a 2" ss(i love/trust sailboat parts) ring on a short loop
the ring will have several purposes
rain water drip point, easy attachment point & keeping my skins where i choose for them to be...
as i disassembled the stock suspension, i took pics of the process & how HH originally rigged the stock suspension
with the pics to refer back to, i was able to replicate the original HH wrap around the attachment point
by replacing the ridge line loop to my new suspension components, exactly like HH did it, my system/hammock/ridge line has not changed, except at the attachment point
"Q"... did the contributors to the OP's information miss a step, or more?
as for the distance between trees needing to be greater, w/ all else the same & just switching to WHOOPIES, the only accommodations one would have to make would be the length of the sliding bury(usually about a foot±) times 2(1 for each WHOOPIE), added to the distance between trees, to make your connections
just pic your own trees...
BTW: my new rigging does a real well job of keeping my LARDUS BOTTOMUS MAXIMUS off the ground
