Head looks to revolutionize the polyester string market with the introduction of their latest offering. The new Head Hawk 18G Tennis String Reel Platinum poly promises to offer a unique blend of playing characteristics unlike any other string. It utilizes a process called Crystal Core Technology. This unique manufacturing process gives Head control over the molecular structure of the string itself, allowing them to engineer different layers with different material properties. The outer layer contains highly oriented molecules, allowing the string to generate stiffness and energy efficiency resulting in a high level of explosive power. Head then gives the inner core of the string a more crystalline structure. This adds a unique level of dampening and touch to the strings performance. The string blends the of both worlds for polyester, allowing for an incredible amount of power while still offering a high level of comfort, touch and responsiveness. The 18-gauge diameter sacrifices a bit of durability in exchange for providing the maximum amount of touch and responsiveness. Head Hawk is an exciting new addition that will appeal to many players as it offers power, control and feel without compromising on any.
