I have used many strings in the past and none have felt as good as the NXT Tour 16. I got these strung on my Babolat racket at 54lbs and I can say that they are powerful but yet give me a lot of control. It is also softer than any of the other ones I have used which improves the feel of my shots. After a few hours of hard hitting with heavy top spin, I noticed very slight wear so I hope they will last. Will update this whenever they break. I highly recommended it.
