I've misunderstood somewhere Joe. If one doesn't "turn" the left wrist on the b/s wouldn't your "unscrewing" motion on the d/s cause you to pull the ball due to a closed clubface? Also, would your motion be considered a compensation per TGM? Thanks for any defogging mate.

The 'unscrewing' motion is a 'supporting roll' (pun intended)

The design of the club is such that left to its own motion, the clubface will 'line up' with the plane of motion/force - open.

Rotation is needed to get it, or keep it, square to the arc - to keep the sweetspot on plane.

If you used the 'twist' on the backswing, but then didn't provide 'support' to keep it there, you'd hit it way right every time. If you 'turn' on the backswing, you simply have farther to 'roll' on the downswing to get back to 'square to the arc'.
