By myself have mounted the strings on my D`Addario EXP16 Martin HD28 after using ropes Martin Light Gauge (after the original strings original factory outlets Martin Medium Gauge). The sound is fabulous and we never tire of playing. After more `a week in a humid country, they sound like new. Well balanced, stuffed d`harmoniques (thank you Martin guitar!). Very pleasant to the touch, its very uniform and ability to make bends from 1/2 tone on the two most high strings without losing the dynamics of other strings in agreement. In short, great!
