Butterfly DIGNICS 64 offers a softer touch and a flat trajectory during topspin resulting in high speed and more pressure for the opponent and hence the power of hitting the balls is achieved at a high level. The strength of Spring Sponge X combined with pimples of code no. 64 - which are also used in the popular TENERGY 64 - create a rubber with highly dynamic capabilities. DIGNICS 64 is recommended for players seeking high-level aggressive play such as speed drive, topspins, smash, etc.
