Haifu Whale II National (Red Sponge) delivers impressive pace, significantly outpacing many traditional Chinese rubbers. Its factory-tuned sponge provides a lively catapult effect, especially in the MAX thickness, granting ample power for decisive drives and finishing loops that allow players to control the tempo of a point.
Spin
This rubber offers excellent grip for generating heavy spin. The grippy topsheet, enhanced by the 'National' selection process, bites into the ball effectively on serves and aggressive loops, producing a sharp, dipping trajectory that challenges opponents.
Control
Despite its offensive power, it maintains a surprising level of manageability. The linear gear system is key, providing predictable and consistent feedback across a wide range of strokes. This makes it reliable for everything from soft pushes and blocks to full-power attacks.
Dwell Time
The combination of a grippy topsheet and a moderately hard sponge allows for good dwell time. This extended contact helps players load the ball with spin and feel, enhancing control during aggressive brushing strokes.
Tackiness
The topsheet possesses a moderate, functional tackiness. It provides solid grip for spin generation but lacks the extreme stickiness of classic Chinese rubbers. This balanced approach contributes to its hybrid feel, offering enough grab for control without sacrificing a responsive, direct contact.
Throw Angle
It produces a medium-high throw angle, particularly evident on looping strokes. This trajectory helps players consistently clear the net with heavy topspin, making it effective for sustained offensive rallies.
