The newest generation of the Idea family, the Idea a12 OS hybrid irons are built with ultra thin faces, perimeter weighting and low CG"s throughout the set. * For the first time in a hybrid club, the Idea a12 OS hybrid utilizes Velocity Slot Technology to produce a spring-like effect across the entire face, which improves forgiveness and increases launch angle without increasing spin * The Idea a12 OS set also includes redesigned Transitional Hybrids with a "Truss Back" design allowing more weight to be distributed to the perimeter of the club * lowering the center of gravity making them optimally suited for bridging the gap between the hybrids and the deep undercut cavity-back irons of the set * This combined with the ultra thin face produces higher ball speeds increasing distance.
