Had the hammock hung today (attached a peak bag & ridge line organizer inside the bug new w/1/16" shock cord).
Tried a structural ridge line from cinch buckle to cinch buckle on my suspension and it didn't work out to suit me.
Looks like I'll just "eyeball" the sag when I hang for now.
BTW - I guessed at the sag today (hanging at home) and hit it perfectly first try! Felt so comfortable I forgot all about the work my wife wanted done today.
