Sets of 9s for an acoustic aren't the most common - most of the time, the choice is these or Rotosound JK9. Of the two, I prefer the Rotosound strings, but that's not to say these are bad, just that I prefer the sound of the phosphor bronze JK9s to the very bright (and somewhat thin) bronze sound of these D'Addario strings.
However, if light, bright, bronze strings are what you're after (they're great for going easy on the fingers of a beginner acoustic player), then these budget strings should do the trick.
