Shaped PolyRound PolySpin
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
- Choose round and shaped candidates with the same gauge and similar stiffness.
- Compare net clearance and bounce height in the same drill.
- 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.
