Babolat RPM Blast 16/1.30 String
Line: RPM Blast
$22.00
One of the most iconic co-polys of all time, this firm and durable string is perfect for big hitters looking to load the ball with pace and spin. The slick surface of RPM Blast enables the strings to snap back with vicious force, resulting in extra RPMs (think heavy ball). It also seems to be working quite well for Rafa! Did we mention the spin?

What players say
RPM Blast 16 is one of the most widely used co-poly strings, known for grabbing the ball and snapping back for heavy topspin. Testers and players call it firm and low-powered but surprisingly comfortable for a polyester, with control that rewards players who can swing fast and generate their own pace.
Best for
- Advanced players with fast, long strokes
- Heavy topspin baseliners
- Players switching from softer poly for more bite
- Modern open-pattern frames (16x19, 16x20)
Pros
- Exceptional spin from the octagonal shape grabbing and snapping back on the ball
- Strong control; testers felt dialed into their targets
- Comfortable for a stiff co-poly, with some calling it among the softer-feeling polys they've tried
- Good durability relative to many spin polys
Cons
- Low power even by co-poly standards, so it needs an aggressive swing to work
- Firm/stiff response that is not ideal for arm-sensitive players
- Loses tension and snapback feel before the string itself breaks
- Not a fit for shorter, slower strokes or players wanting a cushioned feel

The first thing you notice with RPM Blast is the snapback and spin potential. It bites the ball well.
