I agree that long drive competitors need to brace their spine and left leg for maximum stability and I think that goal is best achieved when the spine is straight (extended) and the left leg is straight (extended), and the spine is angled back slightly so that the skeletal axis from the head to the left foot is optimised for power and balance.
Your photos demonstrate that even Jason has considerable secondary axis tilt at impact.
Bigwill - don't apologise for giving me a hard time. Like every forum member, I have to defend the rationale of my opinions.

He is trying to get the clubhead to hit the ball on the ball on the upswing, but he is not trying to hit up at the ball with his hands/central clubshaft. Note that his central clubshaft near the grip end of the club has forwards shaft lean, which means that his thrust action is still down-and-out-and-forward.

Jeff,
That is NOT at impact!

Zuback will have THE MOST extension thru the ball . . . his spine ain't straight though . . . it's major reverse C'd . . . but not at the top.
That is a great picture for hitting really far. To my eye, his power package looks good TGM-wise, but his club is moving up because of the extreme tilt., which is a good thing if you want to win long drive contests.
You might notice how much the tilt has changed from the top. It is much more dynamic to change the tilt in the downswing than to pre-set it at address.
But.....Jason does not have to hit his next shot off the ground like a golfer would.
As for how high they launch it. You might try to find some launch monitor numbers for the long drive guys. It is a big adjustment to actually see the ball when you are standing next to them, because it launches so high.

It is much more dynamic to change from a slight reverse tilt (pivot) at the end-backswing to a large degree of secondary axis tilt at impact. However, I suspect that it far less mechanically efficient than Jamie Sadlowski's swing. He has no reverse tilt (pivot) at the end-backswing position. He has the classical reverse K position seen in Hogan's swing.
