Out of interest - here is a series of images of Mike Austin.
Note that his head is well behind the center of his stance at the end-backswing position. Note the significant amount of secondary axis tilt he has at impact and note the significant amount of upwards tilt of the left pelvis at impact (large positive O factor).
Here is Jamie Sadlowski
Note his head position - behind the center of his stance. Note his significant amount of secondary axis tilt and his positive O factor.

OK Ill bite.
Here is what I think. You keep showing pictures of long drive guys and maintaining that their tilt should represent the norm for a tournament golfers drive technique. I disagree on behalf of anyone who has to hit a second shot. Keep yourself centered and balanced even for the driver*
* unless you have ingrained a compensated but still reliable technique. In the old days many a 9 degree persimmon driver required or even mandated a slight tilt, unbeknownst to the golfer but learned , ingrained over time by the experts.
