Ball Lab: Kirkland Efficiency + v3.0 Yellow Assessment (2025)
The Kirkland Efficiency + v3.0 Yellow is a urethane ball made in the identical manufacturing unit that produces balls for Snell and Vice. We measured weight, diameter, compression, roundness and stability throughout 36 balls and three packing containers to present you an goal have a look at what you’re getting while you purchase the Kirkland.
Right here’s what the 2025 Kirkland Efficiency + v3.0 Yellow seems to be like beneath the microscope.
Kirkland Efficiency + v3.0 Yellow
Execs
Good 100% Good Ball fee — zero faulty balls throughout all 36 examined
High-quartile compression consistency — higher than some premium balls
Cons
Diameter consistency rated C — the weakest class on the cardboard
Compression Symmetry rated C+ — ball-to-ball form uniformity lands in common territory
Our Verdict
The 2025 Kirkland Efficiency + v3.0 Yellow earns a High quality Rating of 84 and a grade of B. It’s constructed on a basis of zero defects and compression consistency that ranks within the high quartile of your complete Ball Lab database. Diameter consistency rated C and Compression Symmetry got here in at C+, which is what stored this ball from scoring increased. It’s additionally price noting that by urethane requirements this ball runs giant and light-weight.

MyGolfSpy Ball Lab measures the standard and consistency of golf balls, giving golfers perception into what’s taking place beneath the duvet. Use Ball Lab as a place to begin in your seek for the suitable golf ball. High quality Scores are primarily based on 5 key metrics: defect fee, compression consistency, compression symmetry, diameter consistency, weight consistency. Scores are weighted towards the components that almost all have an effect on efficiency and faulty balls cut back the ultimate rating to mirror real-world high quality.
Take a look at outcomes
The 2025 Kirkland Efficiency + v3.0 Yellow scored 84/100 and earned a grade of B. The headline quantity is constructed on a clear defect report and compression consistency that ranks within the high quartile of the Ball Lab database. Diameter consistency and compression symmetry had been the mushy spots that stored the rating from climbing increased.
Good Ball Fee got here in at 100%. All 36 balls handed inspection with zero flagged defects throughout cores, layers and covers. That’s the absolute best end result on this class.
Compression consistency graded at B+ with a delta of 6.7 factors throughout the pattern; higher than the database common of 9.7. Ball to ball, you’re getting a product that performs persistently.
The place the Kirkland offers some floor is diameter consistency which graded at C and compression symmetry which got here in at C+. These aren’t disqualifying numbers however they’re the rationale this ball lands at 84 relatively than pushing into B+ territory.
Compression
Compression is a measure of how a lot power is required to deform a golf ball. The upper the compression worth, the extra power required. Consistency in that worth issues as a result of a ball that compresses in a different way from shot to shot produces totally different outcomes from shot to shot. Ball Lab measures each ball individually and tracks the common and the unfold throughout the pattern.
The 2025 Kirkland Efficiency + v3.0 Yellow averaged 91.0, placing it within the agency vary of our database. Compression consistency graded out at B+ with a delta of 6.7 factors and a ramification working from 86.5 to 93.2. That delta is best than the database common of 9.7.
Ball Lab additionally measures compression symmetry which is distinct from the delta measurement. The place the delta tracks variation throughout all 36 balls, symmetry tracks how evenly compression is distributed throughout three factors on every particular person ball. The Kirkland averaged 2.0 factors of symmetry deviation, in keeping with the sector common. Every ball within reason internally constant, although symmetry was not the standout class right here: compression consistency throughout the pattern was the stronger of the 2 numbers.

Weight
Weight is one other metric we analyze in these Ball Lab checks. Even small variations in weight throughout a dozen can translate to inconsistent ball flight. Ball Lab weighs each ball to 4 decimal locations.
The 2025 Kirkland Efficiency + v3.0 Yellow averaged 1.6078 ounces throughout 36 balls, within the common vary of the database. Each ball got here in beneath the USGA most of 1.6205 ounces, with a spread working from 1.6002 to 1.6126 and an ordinary deviation of 0.0031. No particular person ball was flagged as an outlier.
Weight consistency grades out at B−.
The charts beneath element the burden measurements in our pattern.
Diameter
Roundness of a golf ball issues. A ball that isn’t really uniform in form can monitor off line on the placing inexperienced or produce inconsistent flight patterns within the air. Ball Lab measures every ball throughout a number of axes to get a real image of its form.
The 2025 Kirkland Efficiency + v3.0 Yellow averaged 1.6851 inches, above the USGA minimal of 1.680, with an ordinary deviation of 0.0013 inches. Each ball cleared the minimal though the pattern did present a slight pole bias on common. Seventeen of 36 balls measured thicker on the pole, two on the seam, and 17 fell inside gauge noise, that means no clear lot-wide sample was current.
It’s price noting that 1.6851 inches is on the big finish by urethane requirements and, mixed with the lighter weight, this ball’s bodily profile sits outdoors the norm for the class.
Diameter consistency graded out at C, the weakest class on the cardboard and the first cause the Kirkland didn’t rating increased.

Ball Lab report card
Every High quality Rating is a weighted common of 5 grades: good ball fee, compression consistency, compression symmetry, diameter consistency, weight consistency. Our scoring system punishes faulty balls extra severely whereas giving better weight to compression metrics than to weight and diameter. This can be a reflection of how a lot compression variation truly issues to ball flight and really feel.
