The new Nickel-Bronze series of D'addario strings is really good. They are very, very strong, it is hard to break them. They last very long on my guitar. They are very friendly in touch, but the sound might be better... Depends what who likes, I prefer more clear sounding strings with higher voicing. These are not that kind of strings, they are much more warm and kinda Matt sounding. Anyway - very good strings which are really strong
