The stock HH line alone, per side weighs 62 grams. The completed whoopie sling, 13' of Amsteel, weighs 17 grams.
That's a savings of 90 grams total for the hammock with full slings.
The biggest benefit to me is that the amsteel basically disappears in the bag. The stock line is very bulky and brittle in comparison.
