Killerspin’s new BLAST is cutting-edge rubber made especially for advanced skill, topspin players looking for extra power. Like Killerspin’s Fortissimo, the Blast’s rubber consists of a hybrid topsheet made of an elastic compound, which generates amazing rebound, as well as a soft compound that helps grab the ball and create more spin. Equal components of natural and synthetic rubber give an extra spring effect. However, the Blast’s topsheet is stiffer than that of Fortissimo, generating extra power for a wicked shot. The Blast also features a made-in-Japan soft sponge, ideal for powerful topspin shots with great control, and German “Torqsion TechnologyTM”, which is stronger than normal tension standards, and gives the rubber an added performance edge.
