The PING G425 SFT is STRAIGHT FLIGHT TECHNOLOGY. For many, that sounds like music from heaven. There are three
technologies at work.

The first is a heavy tungsten weight that moves the CoG towards the heel. Hit the ball out of the center, and physics creates a lot of right-to-left spin.

Massive MOI means that the face will always fight to stay square to create a straighter ball flight.

You have 8 settings with the adjustable hosel to further customize your ball flight.

The stock shaft is counter-balanced. That makes it easier to swing the clubhead, and release it through impact.
