Installation and Setup
This tennis string is intended for professional racquet stringing. It is highly recommended that installation be performed by a certified stringer or an experienced technician to ensure proper tension and optimal performance.
Recommended Stringing Guidelines:
- Tension Range: Consult your racquet manufacturer's recommended tension range. Polyester strings generally perform well at slightly lower tensions compared to multifilament or natural gut strings.
- Pre-stretching: While not always necessary for polyester, some stringers may choose to pre-stretch the string slightly to minimize tension loss.
- Knotting: Ensure secure knots are tied to prevent slippage and maintain tension.
Improper stringing can lead to poor playability, premature string breakage, or even racquet damage.
Usage and Performance
The Poly Tour Pro 125 is designed for players seeking a balance of control, durability, and comfort. Its polyester monofilament construction provides excellent feedback and spin potential.
Playing Characteristics:
- Control: Offers precise control over shot placement due to its low power output.
- Spin: The string's surface allows for good ball bite, enhancing spin generation.
- Durability: Polyester strings are generally more durable than synthetic gut or multifilament strings, making them suitable for aggressive players.
- Comfort: Engineered to provide a comfortable feel, reducing the harshness often associated with polyester strings.
Performance may vary based on racquet type, stringing tension, and player style.
Maintenance
Proper maintenance can extend the life and performance of your tennis strings.
- Cleanliness: Regularly wipe down strings with a dry cloth to remove dirt and debris.
- Storage: Store racquets in a temperate environment, away from extreme heat or cold, which can affect string tension and integrity.
- String Savers: Consider using string savers if you experience frequent string notching or breakage, especially in the sweet spot.
- Restringing: Strings lose tension over time, even when not in use. It is recommended to restring your racquet as often as you play in a week (e.g., if you play 3 times a week, restring every 3 months).
Troubleshooting
