To keep things simple for you, I am going to say that the Titleist T100 iron replaces the 718 AP2, even if Titleist don’t want me to make that comparison.
However, now you know and partly this is because of the new range of models and partly because it is a little different to AP2.
On the naming front, the 2017 introduction of AP3 between AP2 and AP1 on the forgiveness scale was a little confusing, so now the range goes T100, T200 and T300 in order of size.
AP3 took a lot of sales from AP2 because it was a better player iron that had tech and more forgiveness.
AP2 and now T100 are really game improvement irons for Tour players and the T100 will probably take over as the most played iron on tour.
Compared to 718 AP2, the T100 moves more that way because the head has less offset and a thinner top line, which is actually closer to the 718 CB iron.
There is also more bounce and camber on the sole, combined with additional grinding on the leading edge to make it go better through the turf.
These are all minor changes and on the course the sole went through the ground at impact very easily.
The 1.8mm thick face is forged from SUP10 steel and combines feel with reduced weight.
The MOI is enhanced by co-forging dual density tungsten weights into the heel and toe of the head, also only in the 3 to 7 irons.
You can’t see the tungsten inside, which I like, so you have the benefit of this in a head that looks like a blade.
In testing on GC2, the feel was fairly similar to the AP2. It feels like a forged iron and goes like a cavity back, but probably falls between the two for purists.
The slightly larger head of the 718 AP2 gave it the edge on the T100 on my testing, but only by a yard or so.
The set goes from 3-iron down to pitching wedge and it is good to see Titleist putting the loft on their set wedges now as that will help with distance gapping.
Titleist T100 Irons Verdict
The Titleist T100 irons offer better players who like the look of blades with more forgiveness and a lot of options.
The set can be used as is, or blended with the 620 CB short irons to give the benefits of forgiveness and that faster face in the mid and longer irons with the feel of a forged blade style club in the shorter irons.
The T100 short irons are just normal cavity backs and they do the job, but if feel is what you are after then the 620 CB is worth considering from 8 iron downwards.
It is always impressive how much technology Titleist manage to get into a head of this size. They played down the Tour nature of this iron until AP3 came along for single figure players.
Now we can say that these are for low single figure handicappers and the changes to the T100 take it more in that direction.
