Introducing the Pacific PowerLine 17 string, offering the greatest spin generation of the PowerLine series, designed for exceptional power and extreme control. Pacific utilizes their Twin-Coat technology, a double protection coating applied during the surface processing step, to provide a coating that is easy to string as well as limits string notching during play. PowerLine 16 is a unique polymer technology string for more energy return and additional power. Featuring the Pacific Pre-Stretch system, tension maintenance is enhanced, allowing the string to play up to its maximum potential for a longer period. Designed for the player seeking power above everything, PowerLine will give players the power and comfort of a multifilament string, with the enhanced tension maintenance of a solid core construction.
