DHS - Hurricane 9 is a new tacky rubber with four different configurations (colors), with the blue variant being the rubber most similar to Hurricane 3, 8, etc. in the playing properties. DHS - Hurricane 9 Blue has the DHS #22 sponge with a little more power and elasticity, which is also used in the Provincial series of Hurricane 3.
The pink variant has the orange #20 sponge, which also comes from the Provincial series of Hurricane 3. This gives the DHS - Hurricane 9 Pink a softer feel than the blue variant.
Hurricane 9 Green & Violet is softer rubber, more in the style of Hurricane 8-80 but with slightly more speed and less tackiness. For backhand or a controlled topspin game with forehand.
