Iron Heads

Cavity Back Blades
Cavity back designs redistribute some of the head weight toward the perimeter of the club which is the classic game improvement feature to "enlarge the sweet spot". So how large is that sweetspot, you might ask? We figure that it might increase from the size of a pea to the size of a dime.

The concept of a "large sweet spot" in any forged iron head is strictly a relative concept. If you are looking for true game improvement features, you should go with Callaway.
