Frequently Asked Questions
Why is it called 'Extra Duty'?
It uses a denser, more abrasive-resistant felt weave designed to handle the friction of hard courts without wearing out instantly.
Is this ball too firm for players with elbow issues?
Yes, many community members find it 'stiff.' Players with sensitive arms often prefer the Regular Duty version for a softer feel.
What makes this the gold standard for competitive hard-court play?
The premium woven felt provides the most predictable bounce and is the most widely used ball in tournament tennis, making it the benchmark for professional play.
How long does the thick felt prevent premature 'balding'?
The thick felt typically maintains its integrity for 4–6 hours of play on asphalt surfaces, significantly longer than standard championship balls.
