Golfie,
Can you please elaborate on this statement..."The shaft is bent so that it is toe up, is it not?"

Guys, if you think the shaft bending look by Bobby is a shutter speed issue, I suggest you try and film yourself with a moderate shutter speed camera (e.g. 1/1000) and see. The greater the blurriness the lower the shutter speed, or you can be using a high shutter speed but not enough light. With a shutter speed of 1/2000 which you can get on most cheap camcorders these days, there should be very little/no blurriness of the hands. Anyway, the fact is that Bobby has snapped quite a few XXX shafts when loading on the downstroke. Could it be that stiffer shafts are actually easier to break than whippy shafts if you're strong? I don't know...

Tong,
I assume from your response that you tried the experiment and failed? Nuf said.
There may be other issues with the photography. The only inages worth considering for this kind of evidence are stroboscopic. Over and out.

I get what you're saying. Video images exaggerate degree of bend. Understood. But my original point still holds...

Justin,
The clubhead has rotated to the plane. The transition bends the club shaft so the the toe effectively becomes marginally closer to the grip of the club - therefore I choose to say toe up. What good is that. The Lag that Homer believed in was that the shaft would be bent backwards prior to impact. This is a different bend.

PS I wish I had Yoda's gift for writing clarity!

By the way Golfie, I really appreciate your contributions.
Can you please give references in the book regarding your statement above?
Thanks

Leo,
While I do not know the book backwards and forwards. I would suggest 6-C-2-C as the paragraph you seek. Am I wrong to assume that Homer wishes to deliver a clubshaft that is stressed backward?
Also I recall from some other site Homer's experiment where he put a mass (an ounce I think) and realized a bend of of a 1/8th (again fuzzy) of an inch. (Someone please help with the exct details if is is important!) From this he concluded that every 1/8 of an inch of clubhead lag (shaft lag) was as good as adding an ounce to the head of the club.
BTW I don't think this discussion would help anyone's game. I just didn't want anyone to get excited about the massive toe-up "observed" bend from the original pic. Attempting to achieve such a thing would damage more than a few wrists.

Per 7-1, the prestressed (bent) Clubshaft which helps resist Impact Deceleration must be established before -- not during -- Impact.
Yes, everything else being equal, the more stress you place on the shaft, the more Effective Mass, hence more Power. However, I do not think the visual bend you see in the shaft is necessarily beneficial. Someone with more equipment knowledge could elaborate maybe.

An Explanation
The bend in the shaft will occur in a direction opposite to the applied force. The direction of the applied force should remain constant throughout the stroke, however the clubface orientation changes as it gets squared through impact. At that point, the bend (direction of bend relative to an unstressed shaft) in the clubshaft would now be perpedicular to the clubface (approximately) even though it started out somewhat parallel at the top.
