I´ve been a very happy user of D´Addario EJ16 strings for a long time.
Playing Irish/ folk and other.
Playing with Lowden, old Aria, Martin and Takamine guitars lately, I couldn´t be happier.
I don´t remember breaking a string playing live for years.
And we play round 100 gigs per year, 3 x 45 min. gigs, or so.
Of course, good guitar setup helps.
Of course the strings go dull after a few gigs, but with good pickups you forget about it.
Have to change when they eventually loose intonation, which takes a good while of playing.
I get a good price from Thomann.
Very happy here in Finland, don´t have to walk through snow and sleet, they deliver to my door.
