How to read dispersion: lower standard deviation and a smaller shot area mean the tested shots grouped more tightly. Small differences can fall inside normal testing variation, so use the numbers to build a shortlist and confirm it with your own launch conditions. Source: 2026 MyGolfSpy Golf Ball Test.
THE FIT IN PLAIN ENGLISH
Who should play it?
Players whose main fitting problem is getting longer irons to launch, spin and stop.
Z-Star Diamond is not merely the middle-feel choice. Its specific purpose is adding useful iron spin while preserving tour-ball speed and greenside control, making approach shots the key comparison area.
Approach shots
Increased long- and mid-iron spin is the reason to test Diamond against its siblings.
Around the green
Tour urethane maintains high control on pitches and chips.
WHY IT MAKES THE SHORTLIST
Strengths
- Long- and mid-iron spin
- Balanced tour feel
- Greenside control
KNOW BEFORE YOU BUY
Tradeoffs
Extra iron spin can become excess spin for steep or high-spin players. Test it in wind and include your longest approach club in the comparison.
COMPARE BEFORE YOU COMMIT
Three nearby fits
A BETTER WAY TO CHOOSE
Validate from the green back.
- Start at 30–50 yards.Compare launch, check and feel with the shots you actually play.
- Hit mid-irons next.Watch peak height, landing angle and front-to-back dispersion.
- Finish with the driver.Keep the ball that gives you the best overall pattern—not one heroic shot.
