Got one of each during the kickstarter. Tried them out on a hike and they permanently replaced my whoopie slings on both hammocks. They are a bit heavier than the whoopies, but only by about 2 ounces. The ease of setup when tired, out performs the amsteel and is worth the weight penalty. Small enough to pack into my existing hammock sack. The bag is nice and all. Just ended up in a box with all the other bags that gear comes in, and serves no purpose for me past shipping. Atlas straps are $30. These will out perform atlas any day. The only thing to improve these strap, is if they were made in the US.
