Frequently Asked Questions
What does "stopping power" mean?
Stopping power refers to how quickly the ball stops after landing. Higher spin and steeper landing angles create more stopping power.
Which stopping power level is right for me?
Low spin suits faster swingers (>90 mph) in windy conditions. Mid spin works for most golfers. High spin helps slower swingers (<80 mph) hold greens.
