Yoda - thanks for replying.

I can understand the concept of a sweetspot inclined plane being different to the clubshaft hosel inclined plane, and how the angular difference is at its maximum near the low point of the swing, and at its minimum at the end-backswing and finish positions. However, the angular difference is very small in practical terms, and presumably it is sufficiently accurate to roughly trace the SPL with the right forearm/PP3. Prior to reading the TGM book, I used to use lay-back when hitting out of bunkers or hitting flop shots. However, I simultaneously allowed my arms to steer towards the target while using a vertical hinging action, and my left arm could be closer to the ball-target line than the inclined plane. My question is whether it is very important that I should deliberately learn to ensure that I trace a SPL in the followthrough phase of the swing while using vertical hinging?
