Nike Slingshot 4D
As key demands change from forgiveness and playability to control and accuracy, the Slingshot 4D irons boast four distinct design differences as you work down through the set – position of the rear slingback, sole width, degree of offset and overall clubhead profile.
Verdict
To my ear, the Slingshot 4D has a much better sound and feel than previous Slingshot models, and a solid feel off the face. Perhaps most surprising of all was that ball flight wasn't too high considering the depth of cavity.
