Unused winch cable seems to sell in the $35-75 range - to goobers like me who were rehabbing PTO winches and wanted a nice pretty cable on it. I'd sell it unmounted/uninstalled. I don't need one at the moment, but on CL or here, I'd think it would sell pretty easily. What you will get for it will barely offset the cost of the synth. cable. I'd just run the steel until it's mangled or unfriendly, if you're an infrequent user.
