Very interesting vjcapron!!!

So it depends WHEN(at what stage) the LEFT WRIST is ARCHED or CUPPED(actually FLEXION or EXTENSION) during one's pattern?

Your explanation makes sense. More should be looked into involving this.

The DUVAL, LIETZKE, TREVINO, type of POSITION AT THE TOP is then actually SHUT? They then must make some type of compensation at Impact to OPEN the face... could be Angled Hinging.

Let's get MORE INPUT ON THIS SUBJECT!!

Lagster,

I, too, think this is a very interesting topic and that it has not been studied enough. I guess that the complexity surrounding the different wrist positions and the resulting effects on the clubface is a good reason to just keep the left wrist flat and to maintain the left arm flying wedge as recommended by Yoda.

In response to your question about DUVAL, LIETZKE, and TREVINO...and I'll add LEHMAN to the list...yes, their clubface positions at the top are shut! Dead shut!

What do all these players have in common? They all setup open to their target lines. Since they all have strong left hand grips, they all destroy their left arm flying wedges on the way to the top, however they all comply with the law of the flail which enables them to time their clubface rotation shot after shot. We have fairly deep divots in this foursome, and a few back problems, too.

Dr. Jim Suttie would classify these guys as "Shut Face Players" and he has an interesting chapter on how to make these swings work in his new book.
