I've used Martin SP lights (phospor bronze) on my DM and I love the sound. Recently I restrung with medium gauge as I have it tuned to DADGAD permanently and the result has been good.

I tried the same light gauge Martin strings on my Larrivee D03 and the result was awful. I immediately went back to the Elixir strings Larrivee guitars are sold with. I find them to have much reduced finger squeak than the Martin strings.

Each guitar needs whatever is best for it. I keep experimenting (safely).
