Rotos got a new coated string out called the nexus, it's only in four string packs so far, but you can order a separate .130. I have yet to try them out but a good friend of mine has started using them thanks to him working at a music store and getting them early. He claims that the coating is better than both Elixer and DR and that they have a great tone for metal. Has anyone here tried them out yet? Any input on these new strings?
