Babolat RPM Blast

This string is designed for aggressive baseliners who rely on heavy topspin and need precise control. Because it is a stiffer co-polyester, it is best suited for intermediate to advanced players who can generate their own power and want a string that won't lose tension quickly during intense rallies.

The octagonal shape and textured surface are engineered to 'bite' into the ball upon impact. This mechanical grip helps you generate significantly more spin, allowing you to swing faster and hit with more aggressive topspin while keeping the ball inside the lines.

Babolat RPM Blast is a high-stiffness co-polyester string, which means it provides a very crisp, firm feel. If you have a history of tennis elbow or shoulder sensitivity, you may find this string too harsh; it is generally better suited for players who prefer a direct, connected feel over a soft, dampened one.

One of the standout features of RPM Blast is its excellent tension maintenance compared to other polyester strings. While all polys lose tension over time, this string remains playable and consistent for longer, meaning you won't have to worry about your control dropping off as quickly between restringing sessions.

The 16-gauge (1.30mm) is the thicker option, which prioritizes durability and control over the extra feel and spin potential of thinner gauges. If you are a frequent string breaker or prefer a slightly more dampened, solid response, the 16-gauge is the reliable choice.
