Introduction to Golf Clubs Acquired in Japan Nike Slingshot Irons (Japan Model) - N.S. PRO 950GH R-flex, 3-PW (8-piece set)

 

The specified set of "Nike Slingshot Irons (Japan Model) - N.S. PRO 950GH R-flex, 3-PW (8-piece set)" is a remarkably well-made iron set from Nike Golf, known particularly for the ease of use in the long irons.

Focusing on the set composition from the 3-iron (3I) through the Pitching Wedge (PW), here is a detailed explanation of its characteristics.

🏌️‍♀️ Characteristics of the Nike Slingshot Iron Set (3I-PW)

1. Set Composition and Key Features

Item	Details
Club Makeup	8-piece set: 3I, 4I, 5I, 6I, 7I, 8I, 9I, and PW (some models also exist as 4I-PW sets, etc.).
Maximum Feature	The ease of hitting the 3-iron and 4-iron was exceptional for models of that era. This is due to the "Slingshot Technology," which is designed to make the center of gravity deeper and lower as the clubs get longer.
Target Golfer	The average golfer seeking a stable, high trajectory and high forgiveness across all irons in the set. It is particularly suitable for those who prefer to hit long irons with an iron rather than a utility club.

2. Shaft Specification (N.S.PRO 950GH / R-flex)

• Material: A classic lightweight steel shaft.

• Weight: $94.5\text{g}$ (R-flex, uncut).

• Flex (R): Best suited for golfers with a driver head speed of approximately $38\text{m/s}$ to $42\text{m/s}$. The moderate flex makes it easier to launch the ball and helps prevent loss of distance.

• Benefit: In a weight range that is neither too heavy nor too light, it minimizes fatigue, allowing the golfer to swing all 8 clubs consistently.

3. Role of Each Club (Based on typical loft settings of the time)

Because many Slingshot models featured a strong loft ("distance-oriented") design, the long irons (3I, 4I) had particularly high distance performance, covering the yardage gaps that were difficult to manage with iron sets of the time.

Club	Length (Approx.)	Loft (Approx.)	Role
3I	$38.5\text{ inches}$	$21^\circ \text{ to } 22.5^\circ$	The easiest long iron, designed to achieve distance similar to a fairway wood or hybrid.
5I	$37.5\text{ inches}$	$24^\circ \text{ to } 27^\circ$	A key club for gaining distance while aiming for the green.
7I	$36.5\text{ inches}$	$30^\circ \text{ to } 32^\circ$	The standard iron. The most frequently used middle iron, balancing workability and forgiveness.
PW	$35.0\text{ inches}$	$44^\circ \text{ to } 46^\circ$	The approach wedge for improving accuracy to the green, linking the overall distance flow of the set.
