What is MOI?
MOI stands for movement of inertia, this refers to how much the clubhead twists when you hit it off centre. Players who cannot always hit the ball on the sweet spot of the club will be affected by this twist and it will lead to the ball going off course and ruining your shot. If you check out this Nike 5900 driver review you will see that this driver has actually reached the maximum MOI value that is allowed in golf, to make sure that all your drives are straight and long. So if you find you are hitting the ball off centre you have two choices, either get some lessons from a pro to help you improve, or invest in a driver like this one that will compensate.
