The best thing about Elixir strings is their resistance to corrosion. They don't sound as bright to me on my dreadnought-style six-string guitar, but they sound fine on my 12-string and six-string banjo. I tend to stick with extra-light phosphor bronze on the six string, but did send a couple of packs of Elixirs to a friend in Hanoi, Vietnam. The weather there is mighty tough on strings, and my friend says they're doing pretty well when it comes to lasting longer, but he agrees they don't sound as good.
