Babolat Pro Xtreme is the perfect string for players with long, fast strokes. It offers tremendous bite, allowing the player to bring the ball down inside the lines with AMAZING precision. It's also very durable. This string's control on full swings is exceptional. It will allow big hitters to confidently attack the ball without fear of overhitting. Pro Xtreme also has a nice "snapback", which multiplies the player's efforts with heavy topspin that explodes off the court.
