A group of us toured the Carlsbad facility last spring during the TT San Diego Golf Day. We spent some time in the R&D area where yes, they have experimented with carbon and even tested the durability of the competitors clubs. The carbon heads just do not hold up to Titleist standards. Only when they can resolve that issue will you likely see them introduced into a production model.

Titleist has said they looked into it and with all the extra structure needed bridge the carbon into the titanium the weight savings isn't really there. It's lighter for then to just build full titanium.
It's all in the documentary series of TSR videos. "FASTER"

TSR4 with the new face is very forgiving distance wise, above all except Paradym X and png and Tour Edge.

For me I'm glad they don't fall into the carbon for marketing. I hate the feel and sound of carbon.

If Titleist finds a reason that carbon is better than without, they will add carbon.

The new srxn MKII drivers also ditched carbon.

Old school technology. Interesting info, courtesy of chrome search. I understand Titleist's position.

"The timeline starts in 2000, when a team of engineers explored the benefits of using advanced composite materials (a.k.a. carbon) for structural components in golf club designs. After dozens of design iterations, prototypes, and tests, one team branched off to focus their efforts on optimizing the engine of a driver: The face.

TM began working on this project in 2000 and even built an initial prototype in 2003. Carbon is typically used in structures such as performance bikes and is not really designed for absorbing the amount of force produced when a driver face connects with a golf ball.

To be clear, TM isn’t claiming it’s the first to go to market with a carbon-fiber face driver. Cally did it, Nov 15, 2001, with the C4. And while that was an explosive failure, it likely provided at least a hint of inspiration for TM’s foray into the space. The Stealth isn’t even TM’s first carbon-faced driver."

Great info!! Thank you guys, that makes a lot of sense!
Have a great Holiday Season!

From my perspective, Titleist has never been in the golf space to follow trends and what I would call "gimmicks" just for sales. I really believe they produce products after thorough testing and validating before those products reach their customers. The TS lines have evolved since their initial release and preserve similar design with improved performance. If Titleist ever goes away from what we've seen in the TS line, I'm sure nomenclature will change along the way.

I was fit for a carbon driver made by another company, and it performed pretty good, but it lacked feel. The sound was very muted, and the poor drives felt the same as the good drives. I ended up getting fit for the TSR line, and have a driver and two fairway woods on order. I very much preferred the feel and sound of the Titleist woods over the carbon woods.

I was a TM guy for many years. Now I’m a Titleist guy. Driver is the only hold out but that is about to change.

It's a great observation. Integrating carbon into Titleist's designs could enhance both performance and forgiveness. Carbon's lightweight strength might optimize club dynamics. Maybe Titleist is preserving the traditional feel of their clubs, or they're exploring innovations for future releases. What are your thoughts on this?

Titleist clubs are designed to enhance performance and forgiveness, and their R&D department are achieving excellent results in that area. Which I am all about and playing from the shortgrass is what I enjoy in my game.

Those other brands that are integrating carbon in their designs is old school (2000) is an effort to increase distance, as stated in my previous post. Phil could have been an even better player if he could have hit the short grass at a higher percentage rate.

Hakuna matata.

Titleist is not sticking to titanium out of complacency. With the military alloy they are using they feel they can still exceed the durability and performance of carbon for at least a couple of more releases. At the price of new equipment, the last thing I want is to buy into being a beta tester for technology still being developed.
Granted even some Titleist woods can fail, but one of my companions has cracked every driver he has purchased over the last 4-5 years. More than 1 brand and none Titleist.

Thanks for the info, I appreciate it.
