Rackets with Double String Power combine the advantages of rackets with and without a yoke in the heart area of the racket. They have long double vertical strings which provide a high trampoline effect with maximum ball acceleration. Optimal ball control as the double vertical strings provide a tight string bed which means more string contact on the impact of the ball which enhances precision and control. The tight interweaved vertical and horizontal string allows for excellent vibration damping as the frictional resistance in the heart area absorbs string vibration before it is transferred to the frame.
