Tecnifibre X-One Biphase 17/1.24 Tennis String Reel (Natural)

pop and feel

This is my current favourite string. It has a really great feel for volleys and touch shots, and nice pop for serves and groundstrokes. I also like that spin comes easily with the string. Many people think it breaks easily, and, relative to the 16-gauge version, it does break faster. But I still prefer this, because of the immense feel and comfort.
