Babolat RPM Blast 18 is a co-polyester tennis string designed for aggressive players who prioritize spin, precise control, and responsive ball feel. Its octagonal profile and silicone-based surface coating promote string movement and snapback, helping generate heavy topspin during fast, full swings. The thin 18 gauge offers enhanced feel and spin potential compared to thicker versions, although it provides less resistance to breakage.
Intermediate to advanced players with fast swing speeds who generate their own power and rely on topspin to control aggressive shots. Particularly suitable for competitive baseliners who prefer a thinner polyester string and prioritize spin and feel over maximum durability.
