Having played professionally, and having played in two US Senior Opens and over 30 National Championships, I’ll toss in an opinion on golf balls. First, Costco balls are awful now. The Kirkland ball that was good was taken off the market after a lawsuit. The new ball is like hitting cotton.
That said, there is a group of top tier balls that are all excellent. Titleist ProV1 and x, Taylormade TP5 and x, Callaway’s top lines, Bridgestone B series, Srixon. Many of those companies also make very good “second tier” balls that for an average golfer are just fine. The simple truth is, you do get what you pay for with golf balls. The more expensive balls perform better, period. They go farther and are more consistent. I personally use Taylormade TP5 because I like the trajectory control they give me over ProV balls. Most top tier golfers use Titleist, however.
But for those that say it doesn’t matter, well, I disagree. For a new or occasional golfer one of the thrills of the game is that occasional perfect shot, a drive that they hit perfectly, etc. If you want to take that fun, that excitement, out of the game you take away the most exciting part for them. On a drive, the difference can be 25 or more yards between a top tier ball and a bottom tier. For the occasional or starting golfer, that 25 yards, just once or twice in a round, is a thrill that makes the game fun. Or the iron shot that clears a lake versus one that falls 10 yards shorter and splashes.
The truth is, while I have the ability to compensate for a lousy golf ball, most don’t and will lose enjoyment using a lousy ball. My Trackman will allow me to dial in exactly what adjustment to carry distance I need to make. (Trackman and Mevo+ allow you to tell it what ball you are using and it adjusts its data.) But most cannot do that. They just want a ball that goes FAR when they nail it. I’d urge buying from the top line companies, but if losing the balls is an issue, get the second tier balls those companies offer. Both Titleist and Callaway make very good second-tier balls.
