An Inside Look at Lydia Ko's Golf Ball of Choice
When you reach the highest level of professional golf, every single piece of equipment is chosen for a specific reason. Nothing is left to chance. Lydia Ko’s choice of the Titleist Pro V1x Left Dash is a perfect example of a world-class player seeking a very particular set of performance characteristics to complement her swing.
For many years, Lydia played under an equipment contract, most notably with Callaway, where she used the Callaway Chrome Soft X golf ball. However, after becoming an equipment "free agent," she embarked on a journey to build the perfect bag for her game, piece by piece. This freedom allowed her to test everything and select the gear that gave her the best numbers, feel, and confidence. Her switch to the Titleist Pro V1x Left Dash wasn't a casual decision, it was a move to optimize her performance from tee to green.
What is the Titleist Pro V1x Left Dash?
You’ve surely heard of the Pro V1 and Pro V1x, but the "Left Dash" is a more specialized ball that got its start as a Custom Performance Option (CPO) on the PGA Tour. It was a ball that Titleist's tour pros were asking for, and its popularity led to a wider public release.
The Pro V1x Left Dash is an entirely different beast compared to its more famous siblings. Here’s how it’s designed to perform:
Extremely Firm Feel: This is arguably its most distinct characteristic. The Left Dash feels much firmer or "harder" off the clubface than either the Pro V1 or the standard Pro V1x. Elite players who compress the ball often prefer this solid feel for feedback and control.
High Launch, Very Low Spin: The core formula of this ball is to launch high but with dramatically lower spin. With the driver and long irons, this combination is the recipe for maximum distance, as lower spin reduces drag and promotes more roll-out.
Lower Flight Than Standard Pro V1x: This may sound contradictory to "high launch," but it’s about the overall apex. While it launches high off the face, its low-spin nature results in a piercing, flatter trajectory compared to the standard, high-flying Pro V1x. This gives players like Lydia Ko exceptional control in windy conditions.
Basically, Lydia chose a golf ball that helps her launch the ball high enough to create stopping power with her irons but spins significantly less to maximize her distance with the driver and control her flight in crosswinds.

How Does the Pro V1x Left Dash Vary From Other Titleist Balls?
Understanding the differences between Titleist's premium offerings is the first step in figuring out which part of the "family" might fit your game. Think of it as a spectrum of feel, spin, and flight.
Titleist Pro V1
Who it's for: The masses. It’s the best fit for the widest range of golfers.
Feel: Very soft feel.
Flight: Penetrating mid-trajectory.
Spin: Low long game spin, but still plenty of spin for greenside control. It’s the all-around performer.
Titleist Pro V1x
Who it's for: Players who need a higher flight and a little more spin.
Feel: Firmer than the Pro V1, but still feels soft to most players.
Flight: High trajectory. This helps players who need assistance getting the ball up in the air.
Spin: Higher spin than the Pro V1 across the board, from driver to wedge.
Titleist Pro V1x Left Dash (Lydia's Ball)
Who it's for: High-speed players who generate too much spin.
Feel: Noticeably firmer than the Pro V1x.
Flight: High launch, but a flatter, more piercing overall trajectory.
Spin:Significantly lower spin than both the Pro V1 and Pro V1x, especially on full shots. It's built for speed and spin reduction.
Lydia’s choice shows she isn't worried about generating spin, her world-class technique already takes care of that. Her goal is to control spin, keep it from getting too high with her driver, and produce a flight window that she trusts under pressure.
Should YOU Play the Same Ball as Lydia Ko?
This is the real question. While it's fantastic to learn from the best, it doesn't mean we should blindly copy them. The Pro V1x Left Dash is a phenomenal golf ball, but it's designed for a very specific type of player. Playing the wrong ball for your swing is like wearing shoes that are two sizes too small - it's just going to make things harder.
As a coach, here’s my advice on how to determine if a low-spin ball like the Left Dash is a good fit for you.
Run Through This Quick Checklist:
1. What is your swing speed with the driver?
Low-spin balls are primarily built for players with high swing speeds (generally 105 mph or more). Why? Because these players naturally create enough speed and compression to generate adequate spin. If a player with a moderate or slow swing speed uses a very low-spin ball, they risk hitting "knuckleballs" that fall out of the sky and don't have enough backspin to stay airborne, costing them carry distance and control.
If you swing over 105 mph: A ball like the Left Dash could be a great fit.
If you swing under 105 mph: You'll likely benefit more from the standard Pro V1 or Pro V1x, which will help you optimize launch and spin for your speed.
2. What is your 'miss' with the driver?
Do you hit shots that balloon up into the air and seem to lose steam? Do you generate so much backspin that you sacrifice distance and roll? If so, you are a "high-spin player." A low-spin golf ball is designed specifically for you. It will help bring your flight down, convert that "spin energy" into "ball-speed energy," and give you a more penetrating shot.
If your miss is a high, spinny drive: A low-spin model is worth testing.
If your miss is low and you struggle to get the ball in the air: You need a ball that helps you generate more lift, like the standard Pro V1x. A low-spin ball will likely make your problem worse.
3. What feel do you prefer around the greens?
Don't underestimate the power of feel. The Pro V1x Left Dash feels very firm and "clicky" on and around the greens. Some golfers love this, as it provides instant, sharp feedback. They feel the ball "pop" off the face on chips and putts. Others prefer the soft, "cushioned" feel of a Pro V1, where the ball feels like it stays on the clubface a little longer. There is no right or wrong answer here, it’s purely personal preference.
If you like a crisp, firm feel: Test the Left Dash.
If you prefer a softer, quieter feel: The Pro V1 is probably your gold standard.

The biggest takeaway from Lydia Ko's golf ball choice isn't that you should rush out and buy a dozen Pro V1x Left Dashes. The real lesson is in her process. She evaluated her game, identified her needs (spin control, piercing flight), and tested equipment until she found the tool that perfectly addressed them.
Every golfer should do the same. Don't just play the ball your buddy gave you or the one you found in the woods. Be intentional. Ask yourself:
Do I need more spin or less spin?
Do I need a higher flight or a lower flight?
What feel gives me the most confidence on the greens?
Starting with those three questions puts you on the path to finding the right ball. Go to a launch monitor if you can and hit a few different premium balls - the numbers will tell the story. Even without a monitor, go to a par-3 and hit a few shots with different balls. Note the difference in flight, how they react on the green, and how they feel when you chip and putt. Committing to a single model of golf ball for a season is one of the simplest and most effective ways to build consistency in your game.
