This a set of Titleist AP1 irons 4 through PW and A wedge a total of 8 clubs with True Temper XP regular flex steel shafts. The AP1 716s have maximum distance and maximum forgiveness with an extreme 360° undercut cavity that creates a large, thin, unsupported face that increases both speed and launch for more distance. The high density tungsten drives the center of gravity low allowing stronger lofts to create even more speed and more distance. The use of extreme high density tungsten moves weight to the perimeter increasing moment of inertia for speed on off-center hits. These irons are the most forgiving in there class. These clubs have it all Technology, Distance, Accuracy, Feel, Sound, Playability, Performance, Looks and plenty of forgiveness! PLEASE READ REVIEWS! Original cost was $1100, I'm asking $450 or best offer.
