RPM Blast in short
Babolat RPM Blast is one of the most iconic co-polyester strings ever made. When Rafael Nadal showed up at the 2010 Australian Open with this octagonally shaped co-poly, it changed the game. The octagonal structure with high-density co-polyester adds phenomenal rotation to the ball. The slick surface enables the strings to snap back with vicious force, resulting in extra RPMs. One of the most popular co-polys of all time, this firm and durable string is perfect for big hitters looking to load the ball with pace and spin.
Revolve Spin in short
Revolve Spin is a five-sided co-polyester string with two "wow" factors: spin and control. It's a niche string for big hitters who like ripping the felt off the ball and watching their shots land on a dime. The pentagonal shape bites the ball at contact for excellent spin generation. Quite firm and low powered, which is perfect for advanced players because it gives them the needed control to execute their most powerful strokes. At just $8-10 per set, it's one of the best value shaped polys on the market.
