Kev, I absolutely agree. I don't want to get into a lengthy discussion about forward shaft bend (this thread doesn't need to be dragged - no pun intended - in another direction). But the video explanation is very unsatisfying. If the shaft can't keep up with the sweetspot (as mentioned in the video) such that a forward bend is created, then it must be influencing the sweet spot - resisting its forward motion - opposite to the desired resisting its deceleration

...and how does that knowledge influence what you are trying to accomplish in the golf swing?
