Diadem Pro X is the most powerful and firm option for string in the Diadem line. Designed with the help of current pro tennis players, this poly string is designed to provide a stiffer option then the Flash string, with a hexagon cross section. The firmness results in an explosive response off the string bed with adequate spin production from the edged shape.
