since I've tried this set of strings for my Parlor Ibanez AVN6DTS, i fell in love with it.. Even though they are not as long lasting as other strings from D'addario itself or Elixir, but the tone is perfect for what I like to play with my main guitar.
The feel is soft, the playability of the strings is great, the tone is warm and somewhat "dark", also they are less squeaky , and not make noise when freting
If you like to play blues, folk, or other fingerpicking acoustic style, these strings are great and easy on the fingers to let you play for hours
on my girlfriends Washburn dreadnought, also sound great and since she got those, she can play longer, too.
all being said, they aren't the greatest if you want to play mainly strumming, but they shine for finger picking.
