Inspired by one of the world's deadliest predators, this string is the ultimate weapon for serious players. Premium polyester gives unmatched power and the heptagonal profile bites into the ball to give exceptional spin generation.
The Bottom Line: With a heptagonal structure (7 sides), this string falls right in between RPM Blast (8 sides) and Black Code (5 sides) when talking about bite and spin potential. It certainly provided ample topspin from the baseline and allowed me to hit very high and heavy shots, out of my opponent's strike zone. I was able to hit some very effective volleys as well, keeping them low and biting; making my opponent's not only run, but dig for the ball.
The sweet spot was not as generous as other polyester strings, but it was not as punishing either. The one major drawback to this string was that it did not maintain tension very well, which after time resulted in my shots spraying around the court. My serves had good power, accuracy and kick on them so I could keep my opponent's guessing. Black Widow is a great choice for players seeking excellent spin and bite from a monofilament polyester string.
