Does Shaped Poly Always Create More Spin Than Round Poly?

Cross-sectional shape is only 1 variable; snapback and swing path help create the actual result.

Player overview

Shape can affect friction between ball and string, but surface wear, string-to-string friction, pattern, and impact speed all interact.

Measurement guide

  1. Choose round and shaped candidates with the same gauge and similar stiffness.
  2. Compare net clearance and bounce height in the same drill.
  3. After several hours, inspect edge wear and main-string return so you can separate lasting behavior from the initial feel.

Latest measurement

Long-lasting snapback and the result in your swing matter more than shape alone.
