I tried alot of different string sets for my acoustic guitar:
Elixir, Dunlop, Rotosound, other Daddario sets.
Actually I'm not satisfied with this set also, but this is one of those sets I get back to, because I didn't found anything better. At the moment I use it on my Yamaha FG830. Fits pretty good, yet there's lack of something in tone, like it is not that rich. Still I didn't found anything better, so right now
I'll stick to Daddario EJ26.
I never broke strings on my guitar, though I play in different styles, and this string set is not an exception. Also long lasting doesn't matter for me, I play quite often and change strings every month, regardless capabilities of strings. Also don't forget about issue of new strings to sound too metallic, it wears after couple of hours.
Get this strings if you need light blues and jazz sound,
or you're singing and playing some acoustic songs.
