PowerNick 18 has a proprietary 3-layer construction resulting in a thinner string with exceptional "bite" that allows good players to make better shots. The string's central core incorporates multi-stranded Zyex filaments for superior playability. The outer spiral braid provides good gripping action-enhancing spins and slices. A proprietary outer coating makes for easier stringing and greater durability.
While optimum tension will depend on the player's choice of racket and style of play, the recommended range of stringing tension for PowerNick 18 is up to 32 lbs. (14.5 kgs). To allow for the superior tension holding properties and thin gauge of the Zyex string, Ashaway suggests stringing it at 10-20% lower tension than for nylon strings.
