Titleist AP1 and AP2 irons have a very modern appearance, but still retain a classic Titleist look. Both of them have a multi-material dual cavity set, which is beneficial for improving launch angles and overall feel.
Titleist AP1 irons:
A high density tungsten nickel box of the Ap2 is welded into the back cavity of the stainless steel body, which sets the center of gravity low and deep, promoting launch conditions. With a inserted soft elastomer, the underneath gives the club a solid feel, reducing face vibration during off-center shots. They also feature advanced performance, delivering superb balance speed and feel on long approaches, heavy lies in the rough and even from the sand so you can improve your game and lower your scores. Compared with AP2, AP1 irons have a thicker top edge and more offset. So the Titleist AP1 irons are better suited towards the slightly better than average player, who crave for forgiveness.
Titleist 712 AP2 irons:
If you are the low-handicappers who have been looking for a set with a classic design and a touch of forgiveness, the AP2s are your excellent choose. 712 AP1 and 712 AP2 share the main characteristics. The only difference between them is that the AP1 heads are a 431 stainless steel while the AP2’s are a forged 1025 Carbon steel. Besides, there is a new Tuned Feel System in the set. The new system is a co-molded medallion of soft eastomer and aluminum plate aimed to improve the sound and feel. So for the AP2, a softer, more solid feel you would get.
From the suggestions of testers, you will like the feel that AP2 iron gives you for its sweeter sound and tune.
