String manufacturers classify each string based on its highest-rated characteristic. However, you should always look at all 5 ratings — a string in the Repulsion category may also score highly on control.

Best for attacking players, rear court doubles players, and aggressive singles players who want maximum shuttle speed. Typically thin gauge (0.68mm or below) with high repulsion scores but lower durability.

Best for front court doubles players, net players, and those who rely on precision and spin. Feature textured or rough coating for shuttle grip. Medium gauge typically.

Best for beginners, heavy smashers, and players with hectic training schedules. Thick gauge (0.68–0.70mm+) with high durability scores. More forgiving on mishits near the frame edge.

Best for all-around players and intermediates who want versatility without extreme tradeoffs. Medium gauge with moderate scores across all 5 axes. A great starting point if you're unsure.

If you smash hard and play attacking: Repulsion. If you play precise net shots: Control. If you break strings often: Durability. If you want one string for everything: Balanced.
