Answer: three unique structures offering different performances and feel for the slower swing speed player.

Nippon Shaft views the 70 gram weight steel irons shaft category as a fast growing segment as more slower swing speed players (less than 75mph driver) are increasing. Lighter steel irons shafts assisting with higher trajectories and spin rates are needed for these golfers, but which one?

First, let’s define the products.

N.S.PRO 750GH features a unique construction for flexibility and strength, the one-time lightest shaft in the world promotes a mid/high trajectory for enhanced distances. For the slower swing speed golfer seeking a traditional feeling model at a super lightweight.

N.S.PRO Zelos 7 offers a balance of stability, full flexing and super lightweight to promote a high trajectory and spin rate for the ultimate ball control in the air and on the greens.

N.S.PRO 750GH neo is designed to enhance distance and spin, especially when paired with larger modern iron heads that reduce spin. Ideal for golfers seeking a super-light steel shaft that balances the feel between the softer Zelos 7 and the firmer N.S.PRO 750GH Wrap Tech.

“The three models sounds similar, weights and specs too, but what’s the difference?”

The differences can be seen when the “bend profiles” or the shaft structures are plotted in a graph similar to below. From the left to the right side (X axis), or from the tip end to the grip end, all the models have similar tip stiffness but different stiffnesses in the mid and grip sections. The higher the line (on the Y axis), the more firm.

Based on these different bend profiles, different trajectories and spin are achieved as illustrated below.

In conclusion, from the highest trajectory and spin, in order: N.S.PRO Zelos 7, N.S.PRO 750GH neo and N.S.PRO 750GH. Despite the performance and feel differences, it’s best to visit an experienced club fitter to test the three models to find the perfect structure to optimize your swing.
