    FAQ

    Is the Dunlop SX 300 good for beginners?

    It suits players who can generate racquet-head speed. The lighter SX models are a friendlier entry point.

    Dunlop SX 300 vs Babolat Pure Aero: which should I buy?

    Close rivals. The SX 300 for its feel; the Pure Aero for a crisper, livelier response. Feel and string choice usually decide it.

    Is the Dunlop SX 300 arm-friendly?

    It is moderately stiff. Use a soft poly at a lower tension or a poly/multi hybrid.

    What string and tension is best for the Dunlop SX 300?

    A spin co-poly in the low 50s lbs. Shaped poly for spin, multi crosses for comfort, tighter for control.

    Does the Dunlop SX 300 produce a lot of spin?

    Yes, that is its whole design brief.

    Is the Dunlop SX 300 a spin or power racquet?

    A spin-first frame with accessible power, rather than a flat, pinpoint control racquet.
