I just picked up a DL HyperD 1.0 from Dutch and I have to say, that is one amazing feeling fabric! But I don't dig the floppy sides. All of my hammocks either have integrated nets or knotty mods so floppy sides are really just awkward to me. Has anyone done a knotty mod on a double layer hammock? It seems like it should work fine but I don't want to try it on my new hammock only to find out that it screws it up somehow or doesn't work right.
