Nike SQ Machspeed irons
The Nike SQ Machspeed irons are designed to be the longest that Nike has ever made, while still producing a high launch. The two-piece heads have an extremely thin face that helps produce a powerful strike. The Nike Powerbow in the back of the head gives a wider sweet spot.
Verdict
Extremely long, but without losing any forgiveness and still produces a high ball flight throughout the set. One of the busiest looking cavity designs. Some players will find the extra yardage hard to adjust to.
