Dead PolySnapbackNotching
Does 'Dead' Poly Simply Mean It Has Gone Loose?
Lower tension, greater friction, notching, and reduced elastic recovery create different changes.
Player overview
A heavily used poly can lose tension while its intersections notch, the mains stop returning, and ball response becomes dull or erratic.
Measurement guide
- Gently push a main string sideways and see whether it returns to position.
- Record notching depth, total playing time, launch-angle changes, and impact feel together.
- If erratic response or discomfort repeats, consider replacement even when the measurement is not low.
Latest measurement
To recognize dead poly, read snapback, wear, and ball response alongside the tension number.
