I'm making myself a hammock where I'll hem the edges and thread a rope through with a slip knot that goes up to some tree huggers. Would you recommend 7/64" Amsteel, Dyneema IronWire, or another kind of rope? I'm worried the 730 lbs strength on the Amsteel won't be strong enough whereas the IronWire is 1000 lbs... I also need a rope that won't where and tear too much at my rip stop nylon hemming. Oh also, will these carabiners be strong enough?
