You see more pros on TV using a Titleist driver than any other manufacturer, for good reason, but maybe you’re new to the game, lost some swing speed over the years, or struggle with consistency.

You’re thinking “that Titleist driver would be nice, but not for my game. It would just make matters worse.” Titleist begs to differ. How about a lightweight, easy to hit, innovative design for low to moderate swing speeds?

Something that’s easy to swing? Easy to get up in the air? Square at address, but has draw bias to fight the slice? Titleist brings you the answer by way of the Titleist TSi1 driver.

Handicap Range

My Titleist TSi1 driver review starts with addressing the handicap range. The TSi1 driver is best suited for high handicap players, in the high teens. It’s also a good match for beginners and players with slower to a moderate swing speed.

This is due to the “ultra lightweight” design from Titleist. The saved weight does wonders for slower swing speeds, and newer players, but won’t pack a punch for faster swing speeds.

Technical Review

The Titliest TSi1 is a time machine for those who have lost some speed over the years. 40 grams lighter than other drivers in its class, the ease of swing is impeccable.

The all new, unique to Titleist, ATI 425 Aerospace Titanium face is all business, and business is good. “Forgiveness across the face” is something you see with every driver on the market.

What they don’t disclose is the forgiveness is limited heel to toe. The TSi1 ATI face is so strong and flexible, you’ll find similar consistency and distance vertically too. Struck high or low on the face, the ball will keep consistent distance and spin rates.

The ultra thin titanium crown on the TSi1 driver is the thinnest in town, and allows for weight distribution to increase MOI and launch. Titleist was innovative with MOI placement this time around.

The MOI is strategically placed to provide a draw bias. Perfect for battling the slice. The aerodynamic head shape is an appealing look with purpose. Reduced drag increases ball speed.

The TSi1 doesn’t have a weight port, sliding track, or swappable weights, because Titleist is confident the weight distribution is perfect for the target market. For the tinkerer however, the SureFit hosel and endless shaft options allow a golfer customization capabilities.

Shaft Options

The TSi1 driver is meant to be the forgiving lightweight option for golfers with slower swing speeds. That being said, the stock shaft option for the TSi1 is the light weight Aldila Ascent 40.

This 40 gram light weight shaft is available in stiff, regular, or senior flex. If swing speed isn’t an issue, and you are looking for a forgiving slight draw bias, Titleist offers over 100 shaft options at many different price points.

Performance

The Titleist TSi1 comes alive when you put it to work. Behind all those clean lines and classic design, this lightweight monster roars.

The reduced weight makes it a dream to swing. Effortless and fluid. Any lighter and it would be a problem. It’s the perfect balance for a moderate/slow swing speed.

I saw dispersion and spin rates that are as good as it gets. Forgiveness for days with the TSi1 driver. Off center strikes aren’t penalized much, and finding the sweet spot pays off greatly.

Normally forgiving lightweight options generate a lot of spin, but if you take any more RPMs off, this would fall in the low spin category. A lightweight driver should maximize your swing speed, and the TSi1 does just that.

With its improved aerodynamics, many will see an increase in swing speed. The balanced weight savings generate an optimal launch angle, and really maximizes distance.

Titleist made some innovative moves to offer draw bias without a distracting offset, or gimmicks. Strategic weighting offered a slight draw in my shots, yet I was happy with the square look at address.

Lightweight, draw bias, high launch, forgiving, square, strong, long, Titleist. Any more questions?

Looks

The TSi1 is about as Titleist as Titleist can be. The initiated know what that means. Those who aren’t, Titleist is all about clean lines, classic looks, and timeless coloring.

I love the look of the driver. Jet black crown and gray accidents. If Cadillac and Batman had to design a driver, this is what it would look like.

This sleek bomber looks even better at address. My confidence is sky high while standing over it on the tee. It is square and steady, and you know it won’t falter.

Generally each driver release from a manufacturer has improved performance, but also has improved looks. At this point in time, I don’t see how you can improve on this design and color scheme. Good luck to anyone who tries!

Sound and Feel

The overall acoustics and response of the Titleist TSi 1 leaves nothing to be desired. Full, robust, head turning, metallic thud with some bass to it.

Hitting it true provides the most rewarding sound, and it is felt in the hands too. Feedback in the hands is important. It is the only point of contact between you and the club.

The TSi1 driver offers the most feel of any lightweight driver I have tested. I knew when I miss hit without even seeing the ball.

Pros

  • Beautiful design
  • Light weight with power
  • Square address w/ draw bias
  • Easy launch
  • Forgiving across the face

Cons

  • Spin rates are a little too low
  • Not much more forgiving than TSi2
  • No adjustable weights

The Bottom Line

Titleist made a splash with last year’s TS1 being a lightweight option for moderate to slow swing speeds, and made it a tough follow for any club. The bar was set high with the TS1.

Generally speaking, new models contain marginal improvements from their predecessors. The TSi1, with the new shape, and ATI 425 Titanium face, shows incredible improvement from the TS1.

A thinner, lighter crown, and premium lightweight shaft round out a club that would be an upgrade to anyone’s bag. Between the technical advancements, and the accuracy and distance I saw in testing, the TSi1 driver is an absolute winner.


Alternate Choices to the Titleist TSi 1

TaylorMade Stealth HD

The new TaylorMade draw driver, the Stealth HD is going to be the most similar to the Titleist TSi1 in my opinion. It’s a very forgiving driver with a draw bias also.

Callaway Rogue ST Max D

Callaway has their version of a forgiving draw biased driver for 2022 as well. Check out our Callaway Rogue ST Max D Driver review for our test results on that one.

Ping G425 SFT

And last, but certainly not least, the Ping G425 SFT Driver (which stands for Straight Flight Technology) is Ping’s latest draw biased driver.


FAQ

Note – Some of these FAQs were covered throughout the article, but I still get these questions a lot… so here are the “short and sweet” answers to the most common questions:

Is the Titleist TSi1 forgiving?

Yes, the Titleist TSi1 is the most forgiving driver offered by Titliest. It’s going to provide the best strikes on miss hits (off center strikes) compared to the other drivers in the TSi family.

When did Titleist TSi1 come out?

The Titleist TSi1 came out on February 26, 2021 to the public.

Is TSi1 or TSi2 more forgiving?

The TSi1 is more forgiving than the Titleist TSi2 Driver. The next one after that is the Titleist TSi3 Driver, and then finally the least forgiving is the Titleist TSi4 Driver.

What is the difference between Titleist TS1 and TSi1?

The difference between the Titleist TS1 and TSi1 is that the TSi1 is MUCH more forgiving. The TS1 is the previous model of the TSi1 and was released in 2018. But additions such as the proprietary ATI 425 Aerospace Titanium Face and thinner carbon crown deliver more forgiveness across the face. The ATI 425 titanium is thinner, lighter, more flexible, and more durable than normal titanium.

What is the easiest Titleist driver to hit?

The easiest Titleist driver to hit is the TSi1 by far. It has the largest sweet spot, and the most forgiveness with strikes outside the sweet spot.

Is TSi1 draw biased?

Yes, the TSi1 is draw biased. It’s a slight draw bias, but it’s NOT an offset at address though. Titleist moved the weight in the head to change the MOI just enough to make it a draw bias driver.

What is the most forgiving Titleist driver?

The most forgiving Titleist driver is the TSi1 up to this point.

What is the head weight of a Titleist TSi1 driver?

The exact head weight of the Titleist TSi1 is not published by Titleist, however, the head is around 40g lighter than most standard drivers. And, it’s known that the TSi1 is the lightest of the TSi models. The size is 460cc.

Which Titleist driver is best for seniors?

The Titleist TSi1 Driver is one of the best drivers for seniors in my opinion. When we get to that age, our hand eye coordination starts to deteriorate slightly, thus making it harder to hit the ball in the center of the clubface. A more forgiving driver is the solution, and the TSi1 is perfect for those golfers in that situation.

Is Titleist TSi1 driver adjustable?

Yes, the TSi1 is adjustable in the surefit hosel. You can add/subtract loft and lie angle. Check out the full titleist driver adjustment chart for further details.

What driver does Nelly Korda use?

Nelly Korda uses the Titleist TSi1 driver on the LPGA tour.

Why does Nelly Korda use a TSi1 driver?

The number 1 ranked LPGA pro Nelly Korda uses the TSi1 driver because she likes to swing hard and have extra forgiveness on strikes that may be hit slightly off center. She also likes the aesthetics of the club saying…

I really like the look of it. I need to like the look of my clubs. If I don’t, then I can’t hit them.
