Titleist T100 Vs. Mizuno JPX 921 Irons Comparison Overview

Right off the bat, it should be noted that neither of these iron sets are for the feint of heart. If you are a high handicapper or you have just started playing, you would be much better off taking a look at more forgiving, cavity-back irons.

That being said, if you are a mid to low handicapper looking for the ultimate in performance then you probably have a few questions about these iron sets. Take a look as we detail the key differences between these two sets.

Titlest T100 Irons Overview

The T100’s look amazing at point of address. They have a clean “stepped” muscle back design that will please anyone looking for a classic player’s iron set.

Sure, these irons look great and the D18 tungsten makes them pretty explosive off the deck, but we were shocked at how well these player’s irons played from the rough.

We weren’t expecting that kind of performance in the tall rough.

The sleek leading edge of these irons helps you scoop the ball up and gives you incredible launch. In fact, some of the better players in our testing party were able to land dead on the green from the rough with these irons.

The brushed chrome finish of these clubs look amazing in the bag and at point of address. It’s hard to beat the overall look of these irons, however…

Mizuno JPX 921 Irons Overview

The Mizuno JPX 921 Forged irons may not have the clean look that the T100’s do but they outperform them in some important ways.

First of all, the Mizuno JPX 921’s are more consistent. The one-piece forging ensures that you get consistent repeatable distance and flight control.

The Mizuno JPX 921 forged irons also have a better overall feel.

They feature a beveled leading edge and their soles are actually a bit wider than the T100’s as well.

While the T100’s are still superior in the rough, the Mizuno JPX 921’s are actually a bit more forgiving overall.

They also feature more weight in the heel than in the toe so they are better at producing straight shots on off-center strikes.

The Mizuno JPX 921 forged irons have a better feel thanks to the Chromoly used to make them and the unique forging process.

They were also more forgiving. The T100’s provided more distance and better performance from the rough.
