Responding to longtime WAX Nation citizen Goose’s comment yesterday on the concept, here is the “Figure 7” that Mike Austin and Mike Dunaway used to explain the nature of the leading arm and leading side leverage.
I have said before that, even after I stopped trying to model the MCS Golf Swing after Mike Austin’s model, that there is still probably 90% commonality between his and Dunaway’s and the MCS models.
The little differences (both Dunaway’s and Austin’s setups compared to the right-biased “Leaning A” of MCS, the higher trailing impact heel of Austin vs the flat leading heel pivot of Dunaway) are what make up the 10% difference, but on the leverage produced by the leading side and arm, there is no divergence.
Dunaway – The “Figure 7” & Leading Side Leverage
Now, if you disregard anything to do with Dunaway’s head shifting from its starting position to the top of the back swing, the concept of the leading arm and the “7” shape created by it and the shoulders is dead spot-on.
Just watch the coordinated action of the hips & legs leveraging the “drop” into the impact position, and you will see that this is the natural, mechanically-correct and proper way to swing – not by twisting the lower back against resisting hips:
As you can see, Dunaway is not swinging his left arm, but rather the hips & legs are rotating the lower body as his right shoulder drops, and the shoulders return to square without any effort to actually turn them, and he certainly isn’t turning towards the target or trying to “swing left.”
There is your pry-bar leveraging action – the left arm must follow the hips, and with the shifting weight to the leading foot, you are creating a powerful action similar to a judo throw.
And the way to get this action with the MCS model is make sure of that setup, and to get that hip & leg action working properly with the Ben Hogan-inspired “perfect pivot” action.
It doesn’t get any better than that, my friends, and that was what made Mike Dunaway a long-drive long swinger with regular clubs!
