String ChangeCo-PolyesterComparative Playtest
Should You Revisit Tension When Switching Between Polyester Strings?
Sharing a material name does not mean two products share stiffness, shape, surface, or tension maintenance.
Player overview
Even co-polyester products can feel very different because their structures and additives differ.
Measurement guide
- Review the manufacturer's description and any available stiffness and gauge data for the new product.
- Make the first comparison in the same racquet at your reference tension so you can observe the product difference.
- If discomfort or a launch-angle change is clear, do not force yourself to keep using it; adjust at the next string job.
Latest measurement
Do not expect identical response simply because strings share a material family; create a new baseline record for each product.
