Something I didn't mention in my +100: Many of the higher end, mass producers of acoustic guitars outfit their axes with Elixir. I'm not talking boutique brands, I'm talking brands like Larrivée - which can be found at Guitar Center. Why do you think they do this, when they can put $1.99 strings on their guitars? Longevity on the wall. If they work for them, they work for me. Haven't yet switched over my electric guitars to Elixir, because I haven't found the need - but on my acoustic, they are my go-to string.
