Most video cameras take 60 fields (or 30 frames per second) and it's hard to get a good field at just before impact. I've taken a couple of images from my CSwing video analysis program and yes the bends are kind of subtle but they are there. See what you think. Scott Verplank and Zach Johnson. I'm not saying I have the proof regarding shaft flex, or if certain things can be done or not- and certainly there are alot of factors- throwaway etc. that would influence a forward bending shaft. But the above photos of these clubshafts do not necessarily have a forward bending shaft at this point in the swing- if both of these golfers are swingers- which I believe they are- and you have the natural clubshaft "bowing up" that a swinger's shaft has, then when you view that "bowing up" i.e. that upside down "C" from the side as in these photos- then it will appear that the clubshaft is bending forward when it is not. So with so little "bending forward" - and the angle of these photo's - I would think that, that bending forward could be completely attributed to the "bowing up" of the clubshaft- which is the result of the sweetspot lining up with the line of pull/center of gravity application.
