Random unorganized thoughts: Isn't the point to have the shaft 'stressed' at impact? I would think that it would easier to stress a more flexible shaft, but because of that ease, you may stress the shaft too soon. Isn't the only way to 'stress' the shaft by acceleration, not speed? So if you can't maintain the acceleration through impact, the shaft won't be stressed at impact? So could it be that the more shaft flex you have, the more clubhead lag you need?
And a question: I was watching The Passion the other night on DVD and I noticed they flogged Jesus with very whippy canes-- why didn't they use sturdy, straight canes?
