The Babolat RPM Blast Tennis String is the string of choice for Rafael Nadal and countless other world-class players. RPM Blast retains the octagonal profile but enhances spin generation by utilizing a new dye and coating. The cross-linked silicone coating is designed to allow the strings to slide more easily across each other. This serves two purposes: the first is that the string can move easily, effectively allowing the stringbed to play as a more open pattern. The second, of course, is to enhance durability by lessening string-to-string friction. Babolat's RPM Blast is popular among strong baseliners seeking durability and spin to dictate the action.
