Interesting, I noticed the same thing in my swing recently. I Never felt it was a problem but on starting to tape my swing this year, I noticed that I was not clearing my hips on my swing with my driver and the shaft is actually bends towards the target at impact. Probably a big reason I have had a tendancy to hit duck hooks with my driver in the past. I never noticed a lack of distance, but it is a very apparent problem on tape. I haven't been able to fully fix the problem, but it is getting better. I noticed it improved greatly when I kept my weight back, as my head also clearly moved towards the target prior to impact as well. This allows me to turn better. My next step is to take a stronger grip, or actually just one equal to Hogans book. I have alway taken a weak grip as I have always fought duck hooks, hooks and pull hooks that I mentioned. I read a couple days ago in the new golf magazine (pg 50) that using to weak a grip can in fact lead to "an open clubface at the top. To square the club at impact from this position, you probably release the club early...." Something I may have to play around with this week.
Anyways, here is some Pro swing footage you may find useful, although I am not sure if you can download it or not
