The Butterfly Dignics 64 is a high-tension inverted table tennis rubber designed for maximum speed and aggressive direct play, serving as the fastest option within the Dignics series. Like the other Dignics models, it utilizes the highly elastic Spring Sponge X (rated 40∘Butterfly hardness) and an advanced top sheet for enhanced grip and durability. Its defining feature is the No. 64 pimple structure (the same used in Tenergy 64), which gives it a lower-medium throw angle and a flatter, more direct trajectory. This combination makes it exceptionally well-suited for high-speed topspin drives, direct power play, and fierce counter-topspins from mid-distance. While it generates less heavy spin and a lower arc than the Dignics 05 or 09C, its reduced spin-sensitivity and direct ball flight make it highly effective for blocking and fast, punchy shots, often leading to recommendations for players who prioritise speed and a quick-releasing backhand.
