All of these golf clubs sale online. Titleist AP2 Irons were designed by veteran Peter Gilbert, designer of almost every notable DCI iron of the past, with the guidance of Dan Stone, new head of Golf Club Research and Development. Titleist considers the AP2 a "dual cavity design." The first cavity is obvious: it's the top portion of the club, above the elastomer cushion and below the topline of the club. The second cavity is hidden by the tungsten nickel box. Both cavities push the weight to the perimeter, improving forgiveness on off-center shots. Even though Titleist AP2 Irons was created for 4 years nearly, still best sale worldwide and popular during golfer’s world. A proverb says “Good thing stands the test of time”.
