D'Adds are excellent -- I used their nickels for a while and was v.impressed by their longevity. However, I am also a fully convinced Elixir user now. I approached them with a certain amount of scepticism -- surely they can't last as long as people say? -- but by god they do. I like a reasonably bright tone with decent bite, and my last set of Elixirs were still delivering that after 9 months. Yes they're not cheap, but they do work out to be cost effective if you consider how many ordinary sets would die in the same time.
