Why tee up the ball at all?

[EdZ]

Are we seriously considering that the in-line condition (arm and clubshaft), no matter where achieved, is low point?

We intend to strike a ball that lies on the ground, or on a tee that lies on the ground. Low point must IMO be in relation to the ground. Although I must admit I've more to but I understood Low Point to be the lowest point (elevation) in the clubhead's orbit.

There are two perspectives, one of force, and one of the clubhead.

That's exactly right, of course, EdZ.

Retief's moving up doesn't surprise me with that bending left wrist and pull draw of his.

I have some good video on my home cpu. (not at work)

Both ways are options I'd say.....a Bent left wrist is never really recommended tho.....I know we could get into all this about Retief and etc. etc. but he's an exception and plays a pull draw.

Mathew, I was puzzled by the VJ's picture you posted as to why he was hitting the ball so high on the clubface. Here's Tiger's swing in slow motion which includes a closeup of impact and where the speaker says that he hits the ball high on the clubface for a high launch angle and low spin.

You'll notice (in the clip that follows the swing) that although the clubhead is moving approximately horizontal to the ground prior to impact, the loft of clubface, with the ball high on the clubface, is actually hitting the ball up!

I forgot to ask.. Does this mean that his sweetspot is high on the clubface?

Part of the reason, according to Tom Wishon, that many drivers have better results higher up on the face is that many/most are still designed with bulge and roll in the face (a curved surface). This results in the upper part of the face producing a higher launch angle, which when combined with the fact that most folks are not using enough loft on the driver, tends to produce better trajectory and distance than a 'center' face contact.

I've always read you get higher launch along with lower spin up there.

Thought it had to do with CG and not bulge and roll.

Yes it does.

Chapter 4 of Hebron's Secrets and Lies book goes into this in great detail. Bob Bush, former Titleist designer responds to a Q&A from Hebron.

It feels like you're hitting "up" but that's because of how the weight is distributed in the clubface. Mike Tait of SMT says the sweet spot is a smidge up and in from the center of the club. No one has remembered in this thread that the ball moves while on the club face, inside quadrant and all that good stuff, so sweet spot being up and in makes sense to me...Watch Yoda's video with Brian G for good practical driver technique.

I don't have a dog in this fight, just making observations. But besides Phil's shot (Phil says that he hits the driver on the downswing and it's very obvious on film), it almost appears (on video)that the clubhead is being "driven down" by the collision with the ball, as opposed to moving down through the ball. In other words, the club looks to be moving down after impact, but not necessarily before.
