I also think it doesn't hurt to say that what you play can affect the strings you use. I have been a diehard Di'Addario XL .09's for as long as I can remember playing. That remains on all guitars but my Gibson semi hollow. I do .10's on that. It gives it a fuller sound like Kevin said. Since I tend to like that guitar for more mellow playing, I like the robustness of .10's with the hollow body sound. They also seem to make the clean, neck pick up type of playing very articulate.

Yes, strings...hard to describe.
