Never slice the ball again -- the offset design and closed face allows more time for the clubhead to close promoting a powerful draw.
The square head increases the club head's Moment of Inertia (MOI) or resistance to twisting during off-center hits
Major Advantages of square golf heads are Long and STRAIGHT. You will find the new square heads very hard not to hit straight. USGA has a new limit on MOI for this exact reason.(moment of inertia relates to stability on off-center-hits. A key to maximizing moment of inertia is to push weight as far away from the center of gravity as possible.)
