I tried Elixirs on an acoustic guitar some time back and didn't really care for the sound or the feel. I went through 3 sets over the course of about a year and was happier when I went back to Daddario phos. bronze. I had never done anything to my guitar necks apart for rubbing on some Fret Ease now and then and cleaning them with a Scunge until a few years ago a friend introduced me to Duck's Ax Wax which I apply to the neck and strings whenever I change them. It eliminates squeak, gives the neck and strings a silky feel and definitely prolongs string life. Just my experience.
