I don't remember a video, but I did bookmark this:

Yeah I remember something like that, deloft the club and have more forward lean and less down....... was it how to hit tour quality shots? Just guessing.
I think it was the video where Brian went over Phil's keys to victory - knockdown shot. I went to the GOLF website and it's not there anymore as far as I can tell. From what I remember:
1. Take more club.
2. Choke up a bit (not too much)
3. Get a full turn.
4. Let the arms swing a bit more so you can get more lean.
5. Don't hit it hard, you've taken more club.
He also did a short thing on spin loft. You're trying to deloft the club, but making sure not to hit down too much. Also, you want to swing with less power. All this to minimize trajectory and spin.

I'm thinking this is it. Just trying to remember the move that took out the "too much down." Thanks

Sounds good in theory......but the time point when the shaft becomes vertical will coincide very closely with low point, because the shaft is rotating around the hands much faster than the hands are rotating around the golfer. Don't take my word for it........Dr Zick said it. So..............shaft lean, and thus, Dynamic Loft, at impact, will correlate very closely with Attack Angle. Its not a 1:1 law or anything. But you just can't realistically have the shaft leaning well forward at impact but only be hitting down a few degrees. Possible? yes. Realistic? No.

5-6* lean with 2-3* down is a big difference in ball flight than with 5-6* lean and 5-6* down; few degrees make a big difference in spin loft and iron distances
The new Release does change the time point when the shaft becomes vertical. This does make it very possible to come into impact with a delofted club (less dynamic loft) and more shaft lean, as the path at the bottom is no longer asssociated with a circular arc, but more associated with a straight line. Thus the Attack Angle can be realistically lowered while maintaining more shaft lean. What you are promoting is just one way to deliver the club, thanks to this site and Brian, there is another alternative that is a little more flexible.

I'm not "promoting" anything. I'm simply pointing out that you can't realistically produce whatever combination of shaft lean with attack angle that you desire.......despite what you would like to think. In concert with what Zick said, I have found in my own research that the time point when the shaft becomes vertical will often coincide with the clubhead's low point. This is strong eveidence against what you believe. Maybe the team should ask the doctors.

What number do you want me to produce, Todd?
I'll try to do it Wednesday and post it up.

Not Todd, but i'd like to make a request:
1) Please use a 6 iron
2) Forward lean of 5* or more
3) AOA of 3-4* max
then if i may be so bold
Make a swing after the above that matches the amount of forward lean with the same amount of down. Post up both TM screenshots, i think that would be a great example.

How do you plan on showing and measuring the lean of the shaft tip section when the ball is compressed on the clubface? You'd need a pretty strong camera. Sure, TM calculates Dynamic Loft, but how would you account for the virtually inevitable vertical twisting of the face during collision? A scientific experiment to study this issue is certainly possible, but not as easy to set-up as it may initially appear.
I'd start by asking Zick how much reasonable variance from vertical can the player deliver the shaft when the clubhead is at low point.

I think the point is that it isn't the shaft lean that's important. Rather the delivered loft

Right, in theory, two shots with matching ball speeds, AoA's and Dynamic Lofts should result in identical Launch and Spin characteristics, even if one shot was a 38° 8 iron with no shaft lean and the other was a 46° Pw with 8° of shaft lean.

the lower cog of the PW will make a difference so also impact point on the face has to be adjusted.....
