I usually go for D'addario, however, this time I planned to switch to Dean Markley. Turns out my decision was a wise one. Mistakenly I tuned all the strings an octave higher. Under the normal circumstances, strings would have broken, but guess what, these didn't. I was surprised to see the agility when I got to know that I have tuned an octave higher. Please don't try this with your strings. This was just to let people know how good this product is.
