[12 piece bucket]

I don't know . . . . this dude is on to something . . . . As I think Homer was in the earlier editions. I still believe that hand path is the deal. I think some of this can be found in the evolution or maybe "de-evolution" of Mr. Kelley's thoughts on the elbow plane.


10-6-A Elbow Plane FIRST AND SECOND EDITION

The location of the Elbow during Impact is the reference point used for this Plane Angle. This alignment not only allows the Right Forearm to move On Plane through the Impact but also allows the torso to be position at right angles to the Plane - which are the unexcelled alginments for Right Arm Power and Control.
Remember-the Right Forearm cannot become "On Plane" until the Right Elbow becomes "On Plane".

10-6-A Elbow Plane THIRD EDITION

Where the Right Elbow touches the waist is the reference point used for this Plane Angle. It is the "flattest" normal Plane that will still allow the Right Forearm to be On Plane during Impact. This means that normally the Right Forearm will be moving at right angles to the torso - which are the unexcelled alignments for Right Forearm Power and Control.

10-6-A Elbow Plane FOURTH AND FIFTH EDITIONS

Where the Right Elbow touches the waist is the reference point used for this Plane Angle. It is the "flattest" normal Plane that will still allow the Right Forearm to be On Plane during Impact. This means that normally the Right Forearm will be moving at right angles to the torso - which are the unexcelled alignments for Right Arm Power (6-B-1-0) and On Plane "Throw Out" action (2-K).

10-6-A Elbow Plane SIXTH AND SEVENTH EDITIONS

Where the Right Elbow touches the waist is the reference point used for this Plane Angle. It is the “flattest” normal Plane that will still allow the Right Forearm to be On Plane during Impact. This should produce a very flat Angle of Attack (2-B) with reduced Backspin and should be avoided for Short Shots unless it is also part of your Full Stroke Pattern. The Elbow Plane allows maximum #3 Accumulator requiring earlier Release per 6-N-0. This procedure is executed by the Right Forearm per 7-3 and 10-6-B and Elbow Location per 6-B-3-0-1.

I think it's interesting that some of the "unexcelled" alignments for Right Forearm power got yanked. I think he had it. I'm not physics guy but it seems to me that you get the most effective motion when something is moving at right angles to the axis of rotation. Now we've certainly established that the hands don't move in a straight line or in a true circle. But I think there is an optimum hand path (maybe optimum for the type of shot as well). Homer was on to this for sure. Not sure why he let it go. But I think the colored statements in the 1st thru the 5th are very interesting. For some reason these were "deconstructed" in the 6th (who knows what would have made it in the 7th).

So check these out on their own . . . .

I think there's a lot to be learned from the above. We can certainly has them out and I think they work well with what No-Mind has submitted here. May not be exactly the same deal . . . but close I think.

If you look at most of the pros . . . I'd submit that the vast majority of the pros end up on the elbow plane thru the ball. They may do some dynamic shifting before and afterward (which effects all the vectors of face and path) . . . but for power and precision these cats are on the Elbow-Plane. Why? I believe that it produces the hand path that produces the best mechanical advantage.

Another thing to D's point about Straight Line Delivery . . . . I think an important thing to remember is . . . that is a CONCEPT . . . not what actually happens. The actual amount of what could be even considered Straight Line Delivery is not very long on the arc. I think the Straight Line Delivery concept can no doubt help TONS of golfers . . . to a point. But if you over cook that you can get off Plane quickly . . . .the hands have to go back up and in On Plane . . . it may suprise some how early the hands start working back IN in order for the club to continue down and out On Plane. You can get tons of right vector if you have your hands traveling "out" off Plane late in the downswing.
