The Adams Idea a7OS irons are a great option for players with a higher handicap, those that have trouble making consitent contact or newcomers to the game. The full set includes hybrids, hybrid-irons and traditionally shaped irons. The hybrids replace the long irons and feature a 44 gram rear weighting system to increase launch angles and stability. The mid-irons are a combination of Adams hybrid and iron designs. They feature rear weighting as well as a vibration dampening system for improved feel. The short irons have a more traditional look and have a deep, low Center of Gravity to promote higher launch angles for soft landings on approach shots. Heel-toe weighting increase the Moment of Inertia to give you maximum forgiveness.
