I thought face represents about 85% of initial direction, but that the path (relative to face) determines flight.
Ok, with everything we've learned about D Plane does Swing plane and the line golf instructors love to draw really matter anymore.
'True Path' determines flight. AoA and the horizontal plane determine the 'true path.'

jim,
so in your experience, once you have felt a "zeroed" (or close to it) path, it is reasonably easy to recreate?
thanks
Instead of forcing myself to try to learn a perfect path, with my better understanding of D-Plane, I'm working on finding a way to get my club face just a bit more open at impact, whether that be through a weaker grip, or opening up the face slightly at setup.
Ill be doing a very interesting (hopefully) plane angle experiment in the next few days.
Eh, it didnt turn up the exciting results that I thought it might. I hit some drivers off my knees and they all flew straight. On video at impact the shaft angle was barely 15 degrees or so but came up at 30 degree VSW on trackman. I was hoping to get it up higher than that to really show that shaft plane angle wasnt really that important.
And obviously the ball flew straight from severe heel contact. Sorts proved my point but wasnt that exciting enough to post. Ive seen some very vertical looking 6 irons that come up 55 and some orthodox ones that come up 66. Sweetspot vector is alot different than shaft plane angle.
I think it is very interesting. Now if I thing about bulge and roll and then lay the shaft on the ground, the roll becomes the bulge and vise versa.
So, I guess that would be an above center hit.
Also if you forward lean the shaft you actually open the face.
Were the numbers all hook numbers that flew straight?
They were severe hook numbers and all the balls flew very sraight to a little fade. The forward lean at that plane angle actually just squared the face.
Actually a great example would be Justin Rose whose numbers for a 6 iron (if I remember correctly) were something like 3 or 4 dgrees positive (in to out) swing path and 1 degree open (closed to path) face. This should have resulted in a ball that started out to the right slightly and had a noticeable draw. However, his spin axis was positive (fade). He hits in to out closed face, heel fades.
