The durable and control oriented response of Luxilon ALU and other Luxilon co-polyester strings has revolutionized professional tennis. By far the most popular choice on the ATP Tour, the co-polyester monofilament construction allows a player to take full cuts at the ball without any loss of control. Players with fast swing speeds also tend to find these strings very spin friendly.
