I think it's also worth pointing out that choice of strings is just one small part of getting the sound you want. Your choice of pick/ fingernail growth & condition, how you attack each note/ chord and how you amplify/ record are all far more important in getting that sound than choice of strings.
For the record though I use d'addario nickel wound acoustic guage 13 - 56. They carry on performing well for me even after plenty of use.
Tone is spot on here...I use fine wet & dry to keep the nails really smooth, still get lots of strange looks.
I have to agree it's the combination of strings, nails, accuracy of playing, what guitar you have, mic setup, what sort of song it is. Also the pick thickness really makes a difference too, I use a thin one for strumming and a thicker one for solos/jazz.
Hope this helps Jack.
