Gauge Recommendation
17 (1.25mm) for most spin. 16 for slightly more durability.
Overview
Babolat RPM Blast Rough adds a textured surface to the familiar octagonal profile of RPM Blast. The result is a string that some testers found eclipsed the spin of the original. It feels softer and more arm-friendly than regular RPM Blast, with a livelier, more powerful response. A great entry-level co-poly for juniors or developing players looking to try their first polyester string.
