Cleveland Launcher Irons. According to Cleveland, golf just got easier with the introduction of the new Cleveland Launcher irons. The Launcher irons have the highest Moment of Inertia (MOI) ever in a Cleveland Golf iron. Designed with tremendous stability, these irons minimize the loss of distance on off-centre shots. The low and deep center of gravity helps to get the ball in the air with less effort. Additional offset makes it easier to square the face at impact resulting in consistently straighter shots. The combination of an extra large cavity and extra large face creates one of biggest sweet spots in all of golf. Every shot will be longer and straighter. Launcher irons are made from 17-4 stainless steel and are offered with True Temper Action Lite steel shafts or Cleveland Golf’s very own Action Lite graphite shafts.
