How to Choose the Right Set Makeup of Sterling
Irons® for Your Game

It is critically important to us that you choose the correct set makeup of Sterling Irons® for your swing speed and for your playing ability. It is no good to us or to the golfer to have irons in their set that they cannot hit well enough to have them be a part of your set. This chart will help you decide which set makeup is going to be best for your game. As always if you have questions of any nature about the Sterling Irons® or about any element of golf club technology, we welcome your questions and we are always glad to help with the best information.

Set Makeup Selection for Sterling Irons®

Set Makeup Current 7-iron Carry Distance*
4 iron to SW 165 yds and more
5 iron to SW 145-164 yds
5 hybrid, 6 iron to SW 140-155 yds
6 iron to SW 130-145 yds
7 iron to SW 129 yds or less

Or

Current 7 iron clubhead speed
85mph or higher
79-84 mph
72-78 mph
65-71 mph
64 mph or lower
An accurate 7-iron clubhead speed is preferable to the carry distance as a data point for set makeup selection.

* – based on a 7 iron loft of 33*. For each 2* your 7 iron loft is lower, subtract 5 yds from the entries in the current 7 iron distance to obtain your recommended set makeup

Note: The Angle of Attack also affects the set makeup selection. The more steep/downward your Angle of Attack of the club coming into impact, the more difficult you will find it to elevate the shot high to fly and carry. If you are more steep than a -3* Angle of Attack as read by TrackMan or FlightScope, subtract 5 yds from the entries in the current 7 iron carry distance to obtain your recommended set makeup.

Examples

Golfer with 150 yd carry distance with 33* loft # 7 iron and a -2* Angle of Attack

Set Makeup = 5 iron or 5 hybrid to SW

Golfer with 140 yd carry distance with 31* loft #7 iron and a -3* Angle of Attack

Set Makeup = 6 iron to SW

Golfer with 145 yd carry distance with 31* loft #7 iron and a -4* Angle of Attack

Set Makeup = 6 iron to SW
