I have seen golfers on the SQUARED SHOULDER PLANE with the driver who hit it great!

The point is that stance width dramatically alters your ability to both a) turn and b)use a steeper plane angle

The wider the stance, the less likely most people are to be able to complete the turn and the more likely they are to be on flatter plane angle, regardless of club being used.

To the extent that 'most' people are lacking the flexibility to turn well and a steeper plane angle 'can' be helpful, this is an area a fair number of players should experiment with.

Many feel a wider stance is needed to stay balanced. While there is some truth to that, I suspect many use a wider stance as a 'crutch' against having good balance in the first place.
