Hey all so I am having a hammock made at the moment. I have the option to add on side tie outs to the hammock body. I was thinking one at the foot end and one at the head end. Thing is Ive never seen them before. They seem kinda cool but I dont know if there really is an advantage to having them or not. I dont want to pay extra for something I'll never use. I also dont want to pass up the chance to have them. So does anyone else have them? Do you use them often? If so .. please explain.
