Whip,
you are correct. However, if you start looking you'd be surprised how many great players do it. All the big hitters, and anytime the others try to catch another gear, they'll go down then up to some extent. Long drive guys have huge verticals. Can't do a vertical if you don't go down first. Is it a compensated radius you have to deal with? Absolutely.......but it s definitely happening.

I am aware that many tour players in fact drop their head, and many who do, hit it far. It is part of their body related procedure which MAY amplify physics and reduce throwaway, but it carries a prohibitive price tag, and a compensation Must be made. Ask yourself this, do you think tiger would really lose distance if he didn't bob his head? Even if he did ( which he wouldn't), His swing speed is 120-125 plus, would it matter if it dropped a few MPHs in exchange for a lot more fairways hit? He is a professional golfer after all, isn't it a little embarrassing hitting only half the fairways...Wouldn't a centered motion create more distance because of the speed created by the efficiency of the motion? and by him not having to create compensating forces with muscular effort, the flow of speed would be less interrupted and the club head orbit less disrupted. Also I guarantee tiger could hit it further and straighter with a longer length driver and a head that does not bob or maybe a lower loft and more forward ball position. tigers stats indicate he needs to hit it straighter off the tee, The nationwide guys consistently average longer distances off the tee than the PGA tour guys, there's a reason Why, accuracy is more Important on the big boy tour than hitting a drive 315 vs 305.

The case could be made that this is what tiger has done for so long it is a personal preference that must be worked around instead of changed per se, nevertheless it is a snare. Probably just by backing it off a little bit tiger would improve his accuracy and still maintain his coveted power, in fact I would bet he hits it further.
