Player overview

The four materials differ in structure, elasticity, and wear, so they prioritize power, comfort, spin, and performance retention differently.

Measurement guide

  2. Choose your two highest priorities among arm comfort, price, spin, and durability.
  3. Compare candidates in the same racquet with the same record-keeping method to narrow the material family first.
