Haifu Penguin (Untuned) is noted for its speed and bouncy effect, offering good pace for close-to-the-table attacks and blocks. This rating reflects its potential to generate faster shots compared to slower, more defensive short-piped options.
Spin
The rubber is noted for its ability to generate under-spin, typical for short pips designed for control and blocking. While not a primary spin-generating rubber like inverted counterparts, it offers sufficient spin for tactical play, especially for underspin shots.
Control
Control is highlighted as a key feature of Haifu Penguin, suggesting it is forgiving and easy to handle for players looking to place the ball accurately. This makes it suitable for players who rely on consistency in their game.
Dwell Time
With its emphasis on control and a good catapult effect, the dwell time is estimated to be moderate. This allows for sufficient ball contact for generating spin on controlled shots and for effective blocking, without being excessively long which could lead to control issues.
Tackiness
As a short-piped rubber from Haifu, it is unlikely to possess the high tackiness found in Chinese inverted rubbers. It is expected to have a standard, non-tacky surface typical of European or Japanese short-piped rubbers.
Throw Angle
Based on descriptions of good control and a balance of speed and power, a medium throw angle is inferred. This would allow for a versatile range of shots without being excessively high or low, accommodating both offensive pushes and controlled blocks.
