How it plays — our read

On the numbers, the SX 300 is built around spin and power. It avoids any glaring weakness across the spec sheet. The weight sits in the accessible-but-stable middle, workable for a wide range of swing speeds. Arm comfort is middle-of-the-road: fine for most players, worth softer strings if you are sensitive.

String and tension recommender

Setup
Multifilament/poly hybrid
Tension
48-54 lbs / 22-24.5 kg
A slightly firmer setup can sharpen directional control. Do not chase control with high tension if comfort drops. Shaped poly at moderate tension for snapback.
