The string x-one biphase is the most effective in this range based on the 3 criteria of playability, durability, and integrity.

The uniqueness of this range is the introduction of a wear indicator, which allows the player to change the string before it completely breaks. This indication manifests with significant fraying of the string at the point of ball impact.
