With the wide range of golf shaft options, you need an informed decision to make the right choice.

Tour AD DI vs. IZ: Overview

Every year, the brand introduces new designs that offer distinct attributes. The Tour AD shaft lineup is expanding significantly to satisfy both new and experienced golfers.

Generally, both shaft designs are similar, but Tour AD IZ has a softer tip. It also has a bit higher balance point, which makes it slightly counterbalanced.

As such, it’ll play better in heavier retail heads, plus it will improve the overall ball feel.

It doesn’t kick as its predecessor does. It typically transfers energy from the handle to the golf club head.

Let’s differentiate between them using some factors as follows:


Flex is the amount of bend a golf club gives during a swing session. It directly affects the amount of bend a shaft will have.

The greater the flex, the more the shaft will bend, and vice versa.

The flex option is a significant difference between the two shaft designs.

Both avail different types of flex options. The AD DI features a stiff flex option, while the AD IZ has the Regular option.

Concerning flex, the AD DI will have less bend amount compared to the AD IZ.

However, if you have a faster swing speed, stiffer shafts will fit you better. Hence, it would help if you chose the Graphite Design Tour AD IZ.

If you want to achieve this, either shaft option will help you get that. However, if you wish for a higher spin option, you should explore other opportunities elsewhere.


Both shafts seem to exhibit a similar feel. The brand website claims the AD IZ is Firm in the butt, medium in the center, and Firm+ in the tip.

Their midsection is also similar.


Regarding appearance, the AD IZ design features a matte black and orange color scheme which is ideal for almost every season. The AD DI design is the inverse of this style.


The legal status of any golf accessory is another essential factor to consider before buying it.

Both shaft designs conform to all these rules, making them legal for use in any golf-level competition.
