Aaron Baddeley Stack and Tilt swing in super slo-motion.
Points of interest are just how still his head remains during the swing, and also his impact position. He has held onto the lag, stopping it from passing his left arm line, grip remains ahead of the clubhead.

Here's the impact screenshot..

Positives for me.

Linear movement with the hips.
Straight right leg.
Upper center remaining over point of tangency.

Sam,

Can you clarify what you mean by "point of tangency". I know what a tangent is, but not sure to what you're referring.

TIA

Slingshot

The strike.

Ah, thank you
