One ball, every round

First, so you know where I stand: I work in golf retail. Nothing here is a link, and nothing here is a pitch.

A robot swung a driver at 85 miles an hour with 11 soft golf balls, and not one of them beat the tour ball used as the control for ball speed (MyGolfSpy, September 2026). The slowest was about 1.4 miles an hour behind it. The test found no swing speed cut off at all: firmer was a little faster, in a straight line, at every speed.

So the thing you have been told, soft balls for slow swings, is backwards. Off the tee, at your speed, the ball is close to a wash. Soft costs you a little and gives nothing back.

Where a ball changes your score

Near the green, and in the wet. On a 35 yard wedge shot, balls with a urethane cover averaged 5,415 rpm and balls with an ionomer cover averaged 3,506 (MyGolfSpy, August 2026). In a second robot test, the non urethane balls at the high end rolled 15 to 20 feet farther after landing on a half wedge (Golf Laboratories for Golf Digest, 2026). And when the ball was wet, urethane kept about 90 percent of its spin and ionomer about 55.

That is the whole picture. The cover matters most, and mostly inside 50 yards. On a 7 iron at speed, the gap between the two covers was under 100 rpm.

Two honest limits. First, urethane is not one thing: the urethane balls in that test differed from each other by about 1,700 rpm on the same shot, so the cover is a category, not a guarantee. Second, nobody has measured what that spin is worth in strokes to a 15 handicap. I looked. A ball that stops 15 feet shorter on a pitch is worth something. I cannot tell you how much, and neither can anyone selling you one.

What price buys

Roughly, a dozen balls costs about $20, about $35 to $40, or about $50 to $60. Price buys spin near the green and in the wet, and in some cases tighter manufacturing. It does not buy distance at your speed.

One more number. In a survey of 3,000 golfers, about half said they lose one ball a round, and about one in four said two or more (Golfshake, 2026). Self reported, so take it loosely. But if you lose three a round, a $58 ball is about $14 a round, and a $20 ball is about $5. That is arithmetic, not advice.

The 3 Ball Questions

For eight years, when someone asked me which ball to buy, I asked three questions back.

1. How much do you want to spend?
2. What do you play now?
3. What would you like to be different in the next ball?

The third question does the work. If the answer is nothing, you are done. Play what you play. If the answer is stop faster around the green, that is the cover, and it is the one thing a ball can change for you. If the answer is go farther, the ball will not do it at your speed, and the money is better spent on lesson W2.

Ball fitting tools, honestly

There are three kinds, and each one has a catch. The free quizzes on the ball makers' sites only ever recommend that maker's balls. The quiz sites that compare brands usually earn a commission on the ball they pick for you. And there is one paid tool, run by a club maker, that compares balls across brands from its own robot data; it costs money and it works best if you already have launch monitor numbers. None of them has published how well its picks hold up for golfers like you. The three questions are free, and they get you most of the way.

Stick With One

Any ball you like, the same one every round. That is my rule, not a study's, and here is why I think it holds. The biggest difference between balls is inside 50 yards, which is where feel and roll out are the whole game. Change balls and you relearn that every round. Pick one and your hands learn it once.

It is also one less decision, and lesson 4 was about how many decisions a round already has.

Your one action this week

Answer the three questions. Pick one ball. Play only that ball.

Not playing until spring? Decide now and write it on the card. Spring starts with one ball.

Next week, the last lesson: ten minutes before the first tee. Two jobs, no fixing.
