Named after one of the worlds deadliest predators the new Dunlop Biomimetic Black Widow 16 provides greater durability with a touch less spin generation compared to the 17 gauge version This string will allow strong players to dictate and attack like never before In their first foray into the geometric string market Dunlop brings a heptagonal seven sided profile to give players a lot of bite on the ball and excellent spin generation Black Widow uses a copolymer construction which is able to give players impressive durability in a more player friendly package The high tensile strength extrusion process results in a highly durable string while the copolymer mixture allows for increased feel and surprising amounts of power This string is perfect for the power baseliner who uses spin to dictate points with hard heavy groundstrokes Due to the geometric nature of this string durability will be slightly lower than round polyester strings but the trade off comes back with the spin and power that can be generated
