The installation of my Titleist GTS driver changed my entire golf season

A few months ago I had the opportunity to return to the Titleist Performance Institute in Oceanside, Calif., and get ready for the new GTS series with my now permanent estimator (please, Titleist): Hunter Brown. The GT list was not available in my wallet, except for the GT1 3Tour, so I was eager to try the new GTS system and see what it could do to get a driver in my wallet from Titleist.

There are a few very important changes that have been made to the list that have been huge advantages for me. The biggest thing I knew before walking in the door was the addition of double weight on all models, which is a huge improvement for a player like me who does better with rear weight. My strong Hunter and I had exchanged some messages about fitness and he had shared a great pleasure for me in particular. I went in skeptical, but I left a big believer. Here is the reason.

During the measurement we had the opportunity to run through the entire program. We started with GTS3 as a sort of preview of what was to come in due course, and at the first turn my first reaction was “sold”. It turned out to be a lot better for me, and we had done nothing but match the build I was in with the GT3. We hit the “Gamer” GT3 before we got into the new heads, and it showed its flaws in my swing, as well as other demons I had been battling at the start of 2026 regardless of what product was in my hands. Even a few turns later with the GTS3, where I missed the duck, there wasn't much to complain about. The ball was still in the fairway. At this point, I was locked in the spray booth and Hunter was in control of me.

Before we hit GTS2, Hunter also made a really cool statement that stuck with me in all its merits from a mechanical geek's point of view. He pointed out that if you keep the loft the same, there are 22 different CG positions you can put the system in. This was a different way of saying that there was a driver on everyone's list. By saying that he will keep the loft the same and have many different positions, he was referring to the idea that all three new heads now have double weight front and back. The GTS3 and GTS4 also have foot-to-toe weight on the front track.

Over the past few years, we've started hearing OEMs talk about driver programming in different ways. Most of them talk a lot about how the drivers fit different types of players and how these programs can be so dialed in every swing, but I've never heard a conversation that suited me so much about the CG area before. But it makes sense. The CG area helps determine performance from the strike. Comparing proper CG to not only where the player hits it in the face but also how that face comes through on impact is huge.

With 22 different positions between 3 different drivers, Titleist now has more power to match players than ever before, and when they combine that with loft offerings and adapter settings, there are over 350 total combinations of Titleist drivers, and that's not including shaft selection. That's why this balance ended up changing my season.

The GTS2 and GTS4 were also excellent in their own ways. The main difference I felt during the measurement was that the GTS2 was a lot easier to turn, and the GTS4 felt much better than the previous generation GT4 due to its return to the 460cc form common to the rest of the series.

The GTS4 is a really interesting driver, and something I'd like to explore a bit more, but the spin profile made it difficult for me to consider it as a player. What is interesting though is that it is not a dying machine. It works very well for players who like to move the ball left to right, but I wouldn't say that it is destroyed by bias in any way. I've been told by some Titleist staff that it works best on Tour for players who like the ball to start left and cut, but it also works well for guys who like to see the kind of straight line that goes up in the air easily but collapses as it lands and comes out. They also did something really cool and took the body silhouette of the TSi3 which is arguably the most popular form of Titleist on Tour staff, and made it the GTS4 with all the great technology they added to the modern lineup. GTS4 also sounds the best of the bunch to me. A very satisfying muted crack with an impact that increases in volume as you add more speed to it.

GTS2 was pretty amazing. I think it does a good job of holding its own away from the GTS3, and has a very different sound profile compared to the GTS3, as does the GTS4. This was something they did on purpose. The GTS4 is a bit more of a muted whine while the GTS2 is louder, inspiring more confidence at the touch of a voice. They all sound great, and what you would expect a Titleist to sound like, but they definitely have different sounds and sound profiles that work for the different types of players each head is aimed at.

With the GTS2, it just sounds too loud and tight to me. Performance wise in terms of speed, turning and launching it was actually close to the GTS3, which is nice to see, and it was probably my first love shift with the GTS3, but there was just something about it that made me want to go back and see how we could actually dial it.

Once we settled on the GTS3 as our starting point, Hunter moved the heavy weight to the rear of the head, and added more weight. The final configuration ended up being 4 grams in the center and 13 grams at the back of the head. We removed the adapter configuration from D4 to standard A1 and it was far from the bombs. The only other change we made was moving to a 10.0º head, which was really more comforting to me than anything else. Having a little more loft makes me feel more comfortable off the tee, and gives me the bigger tower shape I'm after. Living outside of Chicago, everywhere we play is soft, so preparing a roll isn't necessary; it's all about carrying.

I have now played 12 rounds with my GTS setup, and it remains consistent and very successful on the golf course. Hunter always does a great job, and I look forward to the future when I return to eat at TPI with him. This GTS3 is easily the best driver I have ever personally played, and it has completely changed my opinion of Titleist woods. I always felt left out of the hype when it came to Titleist and not for lack of trying. The GTS family finally brought me to the challenge, and finding the benefits of Titleist woods has been a real treat. It also created a new confidence in my game that helped me hit the bag better.
