So has anyone taken the OP's design and turned into an SLS with adjustable RL? Theoretically, couldn't you use a little more rope than he says, cut it somewhere above the hammock, bury one side through the other and have an adjusting tail like you would to make a whoopie sling? Then you'd have your SLS system and still be able to adjust your sag without having to untie the clovehitch! Maybe something to toy around with in the future, but for now I'll stick to separate whoopie slings.
