In its quarter century of dominance, the Titleist Pro V1 has become the golf ball against which all others are measured. That’s not a particularly enlightened observation, but it is an important one. It’s the number one ball in golf on Tour and with consumers by, oh, I don’t know, at least a mile—maybe more.
Every challenger, be it a new offering from a mainstream competitor or an out-of-left-field Hail Mary from a direct-to-consumer brand you’ve never heard of, tries to call out the Pro V1 for a duel in the street at High Noon. Those challengers find out there are only two types of golf balls in the duel, the Quick and the Dead. And nobody outquicks the Pro V1.
For a brief shining moment back in 2016, the original Kirkland signature had its shot. Our own testing showed that very first K-Sig had what it took to challenge the Pro V1, particularly at $30 per double-dozen. Unfortunately for consumers, that original K-Sig was a unicorn.
Due more to manufacturing limitations than lawsuits, the original K-Sig was a brief shining moment in history that COSTCO simply couldn’t replicate. Its subsequent Performance Plus golf balls were, simply put, mediocre at best. They have lived a good life, living off the reputation of the 2016 ball, but testing showed them to be short, spinny and not terribly durable.
Kirkland Version 3.0: A new hope?
COSTCO launched Version 3.0 last year. MyGolfSpy’s Ball Lab rated well below average. Its compression was all over the place, as was its sizing. The Ball Lab score of 45 may have been generous.
