Ball Lab is back. After a hiatus, MyGolfSpy’s manufacturing quality testing program has returned and we’re kicking things off with the ball that needs no introduction. The Titleist Pro V1 is the golf ball you’ll find in the bags of weekend warriors and professionals alike and the one that has quietly become the de facto standard against which every other premium ball is measured. If you’re going to restart a testing program, you might as well start at the top.
For the uninitiated, Ball Lab doesn’t test how far a ball goes or how it feels around the green. What it measures is manufacturing quality: the consistency, uniformity and precision with which a ball is built. Every ball in a sleeve should perform the same way. Every sleeve in a box should be identical. Ball Lab puts that promise to the test with 36 balls across three boxes, measuring weight, diameter, compression, roundness and balance. The result is an objective snapshot of what you’re actually getting when you peel the wrapper off a new box.
For 2026, we’ve updated our scoring system. The new methodology is more punitive towards bad balls and weights compression consistency more heavily than weight and diameter. Generally, scores for the highest quality balls will be a bit higher while poor quality balls will score a bit lower.
Here’s what the 2025 Titleist Pro V1 looks like under the microscope.
Titleist Pro V1 (2025)
Pros
Outstanding control — 100% good ball rate across all 36 balls, zero bad balls
Compression consistency ranked in the top 10 of 106 balls in the database — better than average by a wide margin
Cons
Weight and diameter consistency both rated average
Compression has climbed to 92.5 — a bit firmer than previous generations.
Our Verdict
The 2025 Titleist Pro V1 earns a Quality Score of 93.0 and a Ball Lab Quality Award. Its quality control is the standout: all 36 balls passed inspection with zero significant defects and compression consistency ranks in the top 10 of 106 balls in the database. Weight and diameter consistency come in at average which keeps this from being a perfect score. At US$57.99 per dozen, the data supports the asking price. If you’re already playing the Pro V1, there’s nothing in the numbers to make you switch.

MyGolfSpy Ball Lab was conceived as a means to quantify the quality and consistency of golf balls. As the expression goes, it’s what’s on the inside that counts. By shining a light on quality, we can give golfers better insight into the hidden realities of the golf balls on the market today. We hope you will use Ball Lab as your starting point as you search for your perfect golf ball. For a detailed breakdown of our testing methodology, click here.
Each Quality Score is a weighted average of five Lab grades — defect rate, compression consistency, compression symmetry, diameter consistency, weight consistency — with the most weight on the metrics that affect how a ball plays. Defective balls in the box subtract from the average so a sleeve with bad balls is reflected honestly in the final score.
Test results
The 2025 Titleist Pro V1 scored 93.0 and earned a Ball Lab Quality Award. That score is built on a foundation of exceptional quality control paired with consistency metrics that are solid but not standout relative to the broader field. Of the categories measured, Good Ball Rate came in at a perfect 100 percent. Every one of the 36 balls tested passed with zero defects across cores, layers and covers.
Compression consistency earned a rating of Good, ranking in the top 10 of 106 balls in the database—well above the field average delta of 9.7 points. A compression delta of 5.3 points means the firmest and softest balls in the sample are nearly identical which is well above average for the category.
Compression symmetry (previously referred to as IBCR or in-ball compression range) averaged 1.0 points, also well below the field average of 1.9, meaning compression is not only consistent across the sample but also within any given ball. While you’d think that would always be the case, some manufacturing defects manifest as inconsistent compression across the three points we measure on each ball.
Where the score gets pulled back is in weight and diameter consistency, both of which came in at average. It’s rare for a ball to stand out for either but those metrics are what kept the Pro V1 from pushing even higher up the leaderboard.
The Pro V1’s quality control is outstanding. A 100-percent good ball rate and compression consistency that ranks near the top of the database are hard to argue with. With a score of 93, it still comfortably clears the bar for a Quality Award.
Compression
Compression measures how much force is required to deform a golf ball. The more force required, the higher the compression value. Consistency in the compression value matters. A ball that compresses differently from shot to shot behaves differently from shot to shot. Ball Lab measures every ball individually and tracks the average and the spread across the sample.
The 2025 Pro V1 averaged 92.5, putting it in the “firm” range of the database. The compression delta—the gap between the highest and lowest reading in the sample—came in at 5.3 points, among the best in the database.
Ball Lab also measures compression symmetry which tracks how evenly compression is distributed across each individual ball. The Pro V1 averaged 1.0 points of symmetry deviation, well below the field average of 1.9. In plain terms, the value suggests consistency under the cover with no indication of balls being measurably softer or firmer on one side or another.
The charts below detail the compression measurements in our sample.
Weight
Weight consistency is one of the more underappreciated quality metrics in golf ball manufacturing. A heavier ball flies differently than a lighter one so the tighter the weight range across a dozen, the more predictable the ball. Ball Lab weighs every ball to four decimal places.
The 2025 Pro V1 averaged 1.6091 ounces across 36 balls and every ball in the sample came in under the USGA limit of 1.62. Weight consistency as a category came in at average relative to the field and no individual ball was flagged as an outlier.
The charts below detail the weight measurements in our sample.
Diameter
Diameter consistency speaks to how round and uniform the ball is. An out-of-spec ball can wobble off the putter face or behave unpredictably in the air. Ball Lab measures each ball across multiple axes to get a true picture of its shape. The 2025 Pro V1 averaged 1.6805 inches, above the USGA minimum of 1.68 inches, with a roundness deviation of just 0.0005 inches. Diameter consistency came in at average.
The charts below detail the diameter measurements in our sample.
Ball Lab report card
Each Quality Score is a weighted average of five lab grades: good ball rate, compression consistency, compression symmetry, diameter consistency, weight consistency. As noted, our updated scoring system punishes defective balls more severely while also giving greater weight to compression metrics than to weight and diameter.
