RPM Power in short
Babolat RPM Power delivers more pop than any other string in the RPM range. Made with Babolat's unique CO-PET-C extrusion technology, it packs unprecedented power for a monofilament while keeping good spin. A specially added coating increases snapback for explosive power. One of the most comfortable poly strings available - unlikely to cause arm issues. Excellent tension maintenance means it stays playable much longer than RPM Blast. Best suited for players who play flat or cover the ball rather than extreme topspin.
Revolve in short
Wilson designed Revolve so the main strings could snap back more effectively, multiplying the player's efforts into heavier spin. The tri-polymer construction includes a low-friction additive to make the string more comfortable when swinging at higher speeds. Playtesters found it on the soft end of the spectrum - "felt soft, but not mushy." With great control and lots of spin, Revolve is a solid option for advanced players and experienced intermediates. As a budget-friendly option, it's significantly cheaper than similar strings like RPM Blast.
