Titleist

What it does: An L-shape face made of high-strength SUP10 steel improves distance and forgiveness in a compact shape through the use of tungsten. An average of 100 grams of the high-density material is placed in the heel and toe of the 4 through 7-iron to reduce ball-speed loss on mis-hits. The tungsten also lowers the centre of gravity for a higher launch with less spin. The hollow design supports the very thin face with an internal polymer core behind the centre of the face. A lightweight back plate made of a polymer used in the automotive industry absorbs and redistributes energy.

Why we like it: Milking every metre of distance from its latest T200 iron while maintaining a clean look wasn’t a design goal for
Titleist. It was more along the lines of the Apollo 13 “Failure-is-not-an-option” mantra. First, the look of the iron: the impact screw in back needed to go, and it did. Designers also modified the clubhead slightly to be more sleek in size and shape than the previous version. They also gave it less offset so that it would be more in line with the T100 irons. This is why some tour pros aren’t hesitating to sub these clubs in at the long end of the set.
