Titleist AP1 712 Irons
Titleist AP1 712 Irons has made minor changes that include a squarer toe profile along with a thinner top line design. Based on player feedback and grind work done on tour, the AP2's offer narrower sole profiles in scoring clubs to increase playability and improved turf interaction. The Titleist AP1 712 Irons feature two tungsten weights in the sole of the club that increases the MOI of the club without having to make the head longer. This means that it is very forgiving for its size and Titleist say the shot disperson is smaller than the previoius AP1 model.
Titleist AP2 712 Irons
The Titleist AP2 712 Irons have a more square profile than before, a feature specifically requested by Titleist's Tour players. A forged carbon steel head is aided by a high-density tungsten weight, creating increased playability. Titleist wanted to improve distance control and achieve a more consistent ball speed with the 712 AP2 irons. This was done by increasing the MOI by 7%, without impacting workability or control. A dual cavity design pushes weight to the perimeter for playability without losing the ability to shape shots.
