Adams Golf Idea A12OS 7-GW 4,5,6 Hybrid (Left Hand, Graphite, Regular Flex) 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.
