The Babolat RPM Blast + RPM Soft is a specialized hybrid string set that brings together two distinct versions of the RPM family. This combination is designed for players who want the legendary spin and control of a professional co-polyester but require a more forgiving, dampened feel than a full bed of stiff string provides.
The set is presented in a modern Black (RPM Blast) and Grey (RPM Soft) color combination.
The Hybrid Logic
This setup uses a "Monofilament + Monofilament" approach to balance performance:
- The Power/Spin Engine: RPM Blast (Black) is typically placed in the mains (verticals) to provide the octagonal "bite" on the ball and the necessary snap-back for heavy topspin.
- The Comfort Filter: RPM Soft (Grey) is typically placed in the crosses (horizontals). Because it features a polyamide (nylon) core rather than polyester, it acts as a shock absorber, softening the overall string bed and increasing the sweet spot.
Component Breakdown
Babolat RPM Blast (Black)
- Construction: High-density co-polyester monofilament.
- Profile: Octagonal (8-sided) for maximum friction and ball grip.
- Role: Provides the "dead" control and massive spin potential that aggressive baseline players require.
Babolat RPM Soft (Grey)
- Construction: Polyamide (nylon) monofilament.
- Profile: Round and smooth with an aramid/silicone coating.
- Role: Adds a "plush" sensation to the impact and reduces the harsh vibrations that can lead to arm fatigue, while still being more durable than a standard multifilament.
Best Suited For
- Advanced Juniors: Developing players who need the spin of a poly but need to protect their growing joints.
- Intermediate/Advanced Adults: Players who love the RPM Blast "look" and spin but find it too taxing on their elbow or shoulder over long matches.
- Frequent String Breakers: Those who break multifilaments too quickly but find full polyester too stiff.
Feature
- Color: Black & Grey
- Length: 12 meters / 39 feet (6m of each)
- Gauges: Typically 1.25mm (17g) or 1.30mm (16g)
- Composition: Co-polyester (Blast) + Polyamide (Soft)
- Main Benefit: Spin-heavy control with enhanced arm comfort
