Titleist said that the concept for the original Advanced Performance irons arose as a result of research that indicated serious golfers want performance with great feel, not performance at the expense of feel. The Titleist R&D team's advanced research group has been conducting extensive sound and vibration analysis aimed at reducing the harsh lower frequency vibration that causes poor feel in irons. This research led to combining several technologies and materials in the back cavity of the new irons resulting in a new Tuned Feel System to take feel to a new level.Statistics: Posted by jianghuai — Sat Nov 12, 2011 7:52 am
