I am re-reading the now famous Trackman #4 article www.scribd.com/doc/43971194/TuxenHow to hit a straight shot. Just a simple question, they talk about the tour ranges of Montgomery (-6) path and Perry (+6) path but do you know if this includes the downward component of the swing? If I understand it if Perry is +6 path, and then downward 5 degrees then he is going to need a open face of around 11 degrees to hit a straight shot? Am I understanding this correctly? I am trying to understand why I can swing so far left yet hit the ball straight in my own game. For a while I have been hitting pulls or pull hooks because the face was closed and my path was to the right, or maybe in line. Now I am swinging way left yet I have not changed anything with the face yet the ball is going pretty straight, maybe a slight fade. I am completely guessing with no Trackman that I am 4-5 degrees left, downward 4-5 degrees and a shut face. Does this seem plausible?

It is my understanding that the path needs to be 2.5x the face to hit a shot that curves back to the target.
So a clubface thats 2 degrees closed to the target needs to be hit with a path thats 5 degrees left of the target to hit a fade that starts a little left and curves to the target. I am assuming that this 2.5x formula factors in the down.
I'm not sure about the Kenny Perry question, whether +6 refers to resultant path or not. It would be my guess that it does. That would mean he would need a face about 2.5 degrees open to the target to hit a draw that curved to the target.

Ok, gotta remember the 2.5x formula.
I would love to get on a trackman to see the numbers but I dont care enough to shell out a couple hundred bucks.

Yeah I hear ya. I would love to get on one but I dont believe its critical for playing good golf. It's not like nobody ever hit a fairway or green before trackman.

I think this quote explains a lot.
Aim needs to be understood as swing plane, left or right of the target.
He talks about face angle aligned towards the target, but doesn't he mean at the moment of impact?

Impact is all that matters. I don't know if you have to set up with the face at the target. Somebody suggested to me on another forum that this is how it should be done. I would probably slice it if I did this. I usually just aim everything slightly left at address. I hit pretty much straight balls but I assume that I subconsciously make the necessary alignments at impact just from practice hitting balls.

Anytime face and path are misaligned you're going to put spin (not talking about backspin) on the ball that will cause it to curve in flight either left or right. To hit a straight shot, that is one that starts in the right direction and does not curve in flight, the face and the path must be aligned. Now if you're hitting up (as you should for a drive ) then you need to need to make the necessary adjustments so that at the moment of impact both the face and the path are aligned with the target. If you're hitting down same thing... make the adjustments so that at the moment of impact both face and path are aligned with the target. so if you are intentionally swinging left with a PW so the HSP is left a few degrees, maybe the VSP down 6 to 7 degrees, the face must be closed that same amount, but the spin loft is such that the ball flies straight?

I see what your saying about a "true" straight shot versus a ball that goes straight.
I am a lot more concerned with the later. I highly doubt I will ever have a HSP =0 VSP =0, Face=0 type swing.
