Great post . Lets discuss hook face , straigth away position , aiming point , MOI etc etc . Its more physics than geometry though isnt it? dont know.

Yes the circle model like all models is not perfect . Although the Victoria's Secret brochure just showed up in the mail.... now those models are perfect. So theres an exception to every rule, which in itself is a rule which might have an exception.

But how do you know Im Control, Zigfreid?

Siegfried: How do I know you're not Control?
Maxwell Smart: If I were Control, you'd already be dead.
Siegfried: If you were Control, you'd already be dead.
Maxwell Smart: Neither of us is dead, so I am obviously not from Control.
Shtarker: That actually makes sense.

Merry Christmas O.B. Left

Hah. Thanks for that Chief.

All the best of the season to you and yours double D.

Lets hit a shot with this guy in a circle model below. But foyst another book quote:

Quote:

7-2 GRIP TYPES
............

.........For the “True” Hitter, Moving the Ball back (Hook alignment) or forward (Slice alignment) – always with the Clubface aligned to the Target Line per 2-J-1 – gives straightaway initial direction (2-B). Opening the Clubface (Slice Grip) or Closing the Clubface (Hook Grip) at your normal Impact Fix, produces Pushed Slices and Pulled Hooks and so require a compensating Target Line adjustment to make it square to the changed Clubface alignment.
OK although Homer says Hitters here he is ( per the last sentence of the first paragraph in 7-2 which I didnt include here ) also talking about Manipulated Hands Swingers using this geometry. So the only folks this business would not hold for are the True Swingers , those for whom CF alone squares the face. Which means this geometry applies to just about all of us. We can discuss this more in depth if anyone cares to.

Here's a great drawing followed by one that sucks. But it attempts to illustrate why when a player puts the ball back in his stance (say to hit it low ) and squares the face to the Impact Plane Line (or if you prefer "and keeps the face to his target line " in common speak) he should expect a draw shot tendency. Due to a divergence between face angle and clubhead path . Speaking of which I misspelled tendency in that drawing. BTW this is also how I personally hit a draw shot ... ball back a tad, plane line pointed right of the green or target . HOW BOUT YOU GUYS ? THERE ARE OTHER WAYS .

This squaring of the clubface is Grip Rotation. One face angle of it anyways. Notice how this procedure tends to deloft the club face somewhat. And speaking of which should we mark up 6-H-0 to read" Hitters and manipulated Hands Swingers" ? How about adding "True " before Swingers? "Associate the following with True Swinging". I think so but thats just me. What do you guys think?


Loft angle/ plane angle , clubhead speed etc etc will affect the amount of curvature to be expected of course ..... this model is still very simplistic. Straight away initial flight is questionable but close enough for practical purposes perhaps. We need to talk about all this stuff and more.

The model only shows a circular orbit , a fixed face angle and Angled Hinging. But hey that thing can hit a draw. Or a fade . Nobody should attempt a straight shot not even a model!

This guy can rotate his plane line too.
