Titleist T-Series 2023 Irons Review

Titleist T-Series 2023 Irons Review
The 2023 Titleist T-Series irons see replacements for the 100 and 200 irons and two new models in the 150 and 350.
Titleist T100 Irons Review
The T100 irons feature a forged dual cavity construction with a new stronger back bar to create a more solid feel. The face is CNC milled for more precise grooves and the compact head has a new Variable Bounce Sole that is aimed at elite players who want feel with a bit more forgiveness than blades.

Titleist T150 Irons Review
New to the line-up is the T150 irons, which has a slightly larger head than the T100 to accommodate the Muscle Channel behind the face. The T150 takes the benefits of the previous T100S and brings them to a larger profile head. Combined these features create a little more ball speed and as a result the lofts are 2° stronger through the set than the T100. Like the other T-Series irons, ultra-dense D18 tungsten weights are in the heel and toe to improve forgiveness.

Titleist T200 Irons Review
Titleist are calling the T200 the ‘players distance iron’ thanks to its larger profile and redesigned internal structure. The new chassis is stronger to create a stiffer structure and bring the Max Impact Technology point closer to the centre of the face aims for increased ball speed. Again, there is tungsten and the Variable Bounce Sole to improve forgiveness and CNC milled face for feel.

Titleist T350 Irons Review
The T350 irons take everything from the T200 irons and make them bigger. The design features are the same but the larger heads and tungsten positions make the T350 a game improvement iron that looks more like a players iron.

Custom Fitting Titleist T-Series Irons
Titleist T-Series Irons Comparison Review
With such a wide range of heads there are numerous possibilities for custom fitting. To illustrate this and to review the T-Series irons, we invited our resident reviewer Martin Hopley into the Hogan Studio to check them out, so over to him now:

Whilst Titleist’s previous sets of irons have always been a family, the 2023 T-Series irons are more genetically linked as they continue the same design principles through the range. Their aim is to ensure that the '3Ds' of Distance, Dispersion and Descent angle is consistent through the set.
The Hogan Studio has 4,6,8,W in each set so I was able to test right through the bag to see how each model fared against these 3Ds. As a low single player with a driver club head speed of around 100mph, there would seem to be obvious opportunities to blend a set, but it is only in an SGGT fitting studio with Trackman hitting balls outdoors that you can dial each one in to find the optimum combination.
Titleist Wedge Review
The first thing to note is that the lofts vary from 43° in the T300 and T200 to 44° in the T150 and 46° in the T100. This is nothing new and ensures the peak height of the ball flight remains the same despite the different head construction and levels of forgiveness. However to blend in with the distance gaps in your set, a wedge custom fitting session is recommended too.

Straight away you can see that the T200 and T350 matched each other for height and descent angle. They were much more consistent and that is because the more forgiving head shape gave me the necessary ball speed to get the ball airborne.

The smaller heads of the T150 and T100 were harder for me to get going and illustrates the theme that these models are made for players with above average swing speeds. The larger head of the T200 wedge provided a nice blend of looks and forgiveness. The T350 also looked good for a game improvement wedge with the head fitting in well to the family look.
Titleist 8-iron Review
The 8-irons followed a very similar pattern to the wedges as you might expect from the short irons of the sets. The more compact heads of the T100 and T150 gave good feel, but not as much forgiveness. Again, the T200 stood out for me as the happy medium between size, feel and forgiveness, although the ease of hitting of the T350 certainly made it a contender.
Titleist 6-iron Review
Into the mid-irons now and the 6-iron gives an better overview of each model’s performance, which is why most fitters focus on it. The lofts are all within a degree of 27°, apart from the T100 which is a few degrees weaker at 30°. You will find this with most compact irons as the smaller head will not be as fast or as forgiving so that’s why they have more loft for a higher launch. Most players will not get the carry from it unless that have the necessary speed and accuracy of strike.

As you can see that is not me, so the T100 6-iron was well down on the others. The T150 starts to fall into this category too as the club gets longer. It probably felt the best from this collection but the stronger loft meant a landing angle below 40° so this is less likely to stop on a green. The T200 was the optimum performer but as you get into the longer clubs the sound changes a little due to the more hollow heads. You might expect the T350 to do this too, but whilst it is quite chunky, the feel is nice and solid. If you are a sub-100mph swinger then the T350 is going to be a good choice.
Titleist 4-iron Review
This ability to create launch and forgiveness is more evident in the 4-iron where the T100 and T150 carried around 10 to 15 yards less than the T200 and T350. As expected, the T350 carried the most and had a better landing angle of 37.5°. Of the irons this would be the best choice for me. I liked the looks and forgiveness from the T350 which does have a larger offset at address. However this could be a real option at 4 and maybe 5 iron for most golfers as the T200, whilst forgiving, does not have the margin for error that this offers for high single figure to mid handicap golfers.

It should also be noted that the new U-505 utility 4-iron gave a better landing angle albeit with less carry, so if you plan to use a long iron for approaching a green then read my Titleist U-505 Utility Iron review in full here.

Titleist T-Series Irons Summary
Overall this is another quality set of irons from Titleist. As I hope I have shown, the right model will choose you rather than the other way around and that is why having a through the bag custom fitting, like that at SGGT, will allow you to test each option to find the best set combination for you.

The T100 irons are the most popular irons on Tour and there is a reason they appeal to elite players as they offer performance in a compact head. It’s maybe not as sharp a feel as some other irons in this sector, but you do get more forgiveness than the standard cavity back of this style.
The T150 brings a little more forgiveness with a stronger loft for those with above average swing speeds. However most low amateurs will probably end up with the T200 irons with maybe a T350 at the longer end of the bag. If you are a high single figure or mid handicap golfers then the T350 will be the ideal choice from the middle of the bag upwards or maybe all the way through as the wedges are pretty good for this style of head.
