Yasaka - Rakza Z is a tacky hybrid rubber with a hard sponge "Power Sponge" of around 50°. With incredible spin capabilities and a higher arc than the other rubbers in the Rakza series, this rubber allows for a quick loop / attack game both near and farther from the table. Serves and short returns are accurate with very good control. Because the sponge is softer than with the Rakza Z Extra Hard, the speed properties are slightly lower and also give a slightly higher arc.
Speed (Revspin): 8.8 / 10
Spin (Revspin): 9.5 / 10
Control (Revspin): 9.1 / 10
