Babolat
RPM Blast
Rafa's string. The octagonal cross-section bites into the ball and snaps back for heavy topspin. One of the highest spin-generating polys on the market.

Recommended pairings
Polys pair beautifully with natural gut or multifilament crosses for the classic hybrid setup — more comfort without losing control.
Poly mains + Natural Gut crosses
The "Federer setup." Maximum feel and comfort from gut, maximum control from poly. Expensive but unbeatable.
Poly mains + Multifilament crosses
Budget-friendly hybrid. Softer and more arm-friendly than full poly without the gut price tag.
Full poly (same string)
Consistent feel throughout. Best durability and control. Ideal if your arm handles it well.
