MOI stands for “moment of inertia”. Depending if the term is used on the clubhead or the club itself, it may refer slightly differently.
When used on the clubhead, this technical term measures the clubhead’s resistance to twisting when the ball is struck. For example, you hit the ball on the toe of the clubhead. A clubhead with a higher MOI will twist less as a result of the mis-hit, creating a better chance that the ball will still go where you intended and with less loss of distance.
When used on the club, this technical term measures the club’s resistance to the rotation when swung. In a set of MOI matched iron, regardless if it is a 3 iron or a 9 iron, the resistance to the rotation when swung will be the same. In effect, this will provide more consistency in the set. Translated to swingweigth, it would mean that we now have a sloping swingweight, i.e. long iron will be lower swingweigth and short iron higher.
