Similar to the R1.16, the R3.16 is a control-oriented paddle with a square top design. As such, it feels and performs much the same way. One key difference between the two, however, is the R3.16’s higher swing weight. This extra heft allows for more powerful groundstrokes and makes the paddle slightly more forgiving. The twist weight measurement for the R3.16 was lower than the R1.16 but without knowing those numbers I would have said the R3.16 plays with a little more forgiveness than the R1.16. Nevertheless, it shares the R1.16’s qualities of excellent control, large amounts of spin and requires more effort to generate power though it will give you a little more power than the R1.16.
 
The R3.16 has a slightly denser, plush feel to it while the R1.16 has a lighter, plush feel to it. I thought I could control the R3.16 a little better since it carried through the ball easier at impact compared to the R1.16. However, I did notice a slower maneuverability speed compared to the R1.16, which some players might find limiting.
