If you're worried about resale value, you could completely remove the stock cord and put it in a drawer somewhere. There are much lighter and less bulky options for suspension cord that can be cut to size. Swapping them out isn't hard at all. There is a thread about how to do it, but I couldn't find it. Basically, you would just cut the zip tie that holds the little black sleeve over the knot at the end of the hammock, pull the sleeve back, untie the stock cord and redo the wrap and knot with the cord of your choice. You can easily revert to the stock system if the hammock ever winds up on eBay.
.. truly to enjoy bodily warmth, some small part of you must be cold, for there is no quality in this world that is not what it is merely by contrast. Nothing exists in itself. If you flatter yourself that you are all over comfortable, and have been so a long time, then you cannot be said to be comfortable any more. - Herman Melville
