The speed rating of 5 indicates that the NP-2 is a relatively slow rubber. While some sources provide a slightly higher rating, the overall consensus and the manufacturer's own rating point to a rubber that prioritizes control and spin over raw speed. This is typical for a long-pimpled rubber, where speed is often sacrificed for disruptive capabilities.
Spin
The '10+' rating for spin signifies that the NP-2 is designed to generate a very high amount of spin. This is consistent with its nature as a long-pimpled rubber, which excels at imparting heavy spin, particularly backspin, on the ball. While some ratings are lower, the manufacturer's explicit '10+' and descriptions of deceptive spin and backspin point to its primary strength.
Control
With a control rating of 8, the NP-2 is considered to offer good to very good control. This is crucial for a rubber designed for deception and disruption. The ability to place the ball accurately and manage incoming spin is essential for effective use of long pips. The noted 'forgiving' nature suggests it's manageable even for players not at the absolute elite level.
Dwell Time
The longer pimples and moderate tackiness contribute to a decent dwell time. This allows the player to impart more spin on the ball during contact and provides a degree of control, particularly in blocking and chopping situations.
Tackiness
A tackiness rating of 7 indicates that the NP-2 has a moderately tacky topsheet. This characteristic can contribute to spin generation, especially on serves and softer shots. While not as tacky as traditional Chinese inverted rubbers, this tackiness likely aids in controlling and manipulating the ball.
Throw Angle
The combination of long pips and a medium tackiness suggests a medium throw angle. This allows for lifting the ball over the net with spin, and when combined with the deceptive nature of long pips, can create awkward trajectories for the opponent.
