Babolat RPM Rough - String Reel junior Read our blog on whyBabolat RPM Rough, formerly known as Babolat RPM Blast Rough, is a textured version of Babolat's best selling co polyester string RPM Blast. Made of the same material and with the same octagonal shape as RPM Blast, RPM Blast Rough has a rough texture thanks to the small Babolat logos that are imprinted into the strings surface. The result is a string that has even more grip than standard RPM Blast, which should result in even more spin potential.
