Hi Buck,

Regarding the shaft unloading just before impact, that is what it's supposed to do.

Take a look at this video. You can slo-mo-stop-action the video by pulsing on the pause button. Do this, when the clubhead is close to Tiger's right foot. You will see the unloading. The other neat thing is after impact, you have the shaft recoiling with a reverse bend.


As you know, if the shaft is too weak for your swing, the flexing (loading) will be too great and it will be very difficult to return the face to square
