2. Setup and Installation
The HEAD Sonic Pro string is designed for professional stringing. Proper installation is crucial for optimal performance and string longevity. It is recommended to have your racket strung by a certified stringer.
2.1 Stringing Guidelines
- Tension: Consult your racket manufacturer's recommended tension range. Due to the string's polyester composition, a slightly lower tension (1-2 lbs less than typical multifilament strings) may be considered to maintain comfort and prevent arm issues.
- Pre-stretching: While not strictly necessary for all polyester strings, a slight pre-stretch can help stabilize tension.
- Knotting: Ensure secure knots to prevent tension loss.
- Stringing Pattern: Follow the specific stringing pattern recommended by your racket manufacturer.

The terms 'CONTROL' and 'COMFORT' are highlighted, indicating the string's primary performance characteristics.

4. Maintenance
Proper maintenance extends the life of your tennis string and ensures consistent performance.
- Regular Inspection: Periodically check your strings for fraying, notching, or signs of wear. Replace strings when significant wear is observed or if performance degrades.
- Cleanliness: Wipe down strings with a damp cloth after play to remove dirt and sweat, which can degrade string material over time.
- Storage: Store your strung racket in a racket bag or in a climate-controlled environment to protect it from extreme temperatures and humidity, which can affect string tension and integrity.
- Regripping: Ensure your racket grip is in good condition to prevent excessive hand slippage, which can lead to tighter gripping and increased stress on the arm, indirectly affecting string perception.
5. Troubleshooting
Addressing common string-related issues can improve your playing experience.
- Frequent String Breakage: This can be due to aggressive play, thin gauge string, or excessive notching. Consider a thicker gauge string or a hybrid setup if breakage is persistent.
- Loss of Tension/Dead Feel: Polyester strings naturally lose tension over time. If your string feels 'dead' or lacks responsiveness, it's time for a restring, even if the strings are not broken.
- Arm Discomfort: High tension or stiff strings can contribute to arm pain. The HEAD Sonic Pro is designed for comfort, but if discomfort occurs, consider lowering your string tension or exploring alternative string types.
- Inconsistent Ball Response: Worn or notched strings can lead to inconsistent ball contact and reduced spin. Inspect your strings and restring if necessary.
