bob...surely the other way round? Obviously both are interlinked but I would have thought that swing path determines direction and clubface angle determins spin?But, I did leave school in 1977, maybe the last Labour government change the laws of physics without letting anyone know ;)
I tell you what mate it took me a lot of ear bashing from very well informed people on the site to get me to understand it. I still got down the range to try and prove that it was wrong........guess what I messed about and all of a sudden I was hitting all the different types of shots just by following them.

The old teaching was as you say, the ball starts in the direction of the swing path then spins sideways according to where the club face points. Hence...point your body where you want the ball to start and the clubface where you want the ball to finish.

Here, you can see the ball starts off in the direction of the red line then fades to the right onto the green.

BUT
We now know the ball starts more towards the club face direction then fades to the right due to the swingpath , missing the green right

I thought the same as you and everyone else until I had this same discussion with my PGA tutor in 2004

the bit that confused me is you started off saying the swing path was in to out. But the confusing bit was when you said your pal was aiming way left and slicing back into the middle.

Old or new laws of physics, it's not possible to hit a slice with an in to out swingpath.

That's cool mate. The slice on the in to out path was being caused by how much he had the face open in relation to swing path at impact.

Actually.....................

If you swing in to out at 5 degrees to the target line with a clubface that is 10 degrees open at impact that's a PUSH SLICE, if the face is 6 degrees open it's a PUSH FADE, if the face is 4 degrees open it's a PUSH DRAW.

Forget the PUSH bit, a SLICE is caused by cutting across the ball on an out to in swingpath causing the ball to START LEFT and cut back to the right.

Agreed that a PUSH is caused by swinging in to out, that is a different shot altogther.

Now we get into the area of how you define a slice/fade/draw/hook
Does a slice start left and finish right of the target...or is that a pull slice?

You CANNOT FORGET the PUSH bit. You are also, wrongly, assuming that only an in to out can cause a slice.

As per JO's reply, A fade/slice is caused by a clubface being open to the swingath - irrespective of what the swingpath is! If the swingpath is in to out, then it'll be a PUSH FADE or PUSH SLICE. It just happens that the most common swing faults for most players are having an open face and an out to in swing - which means Fade or Slice! Most pushes, on the other hand, also include an open face, but not open enough to add much fade, so 'straight' push (face square relative to the swingpath). So it's Einstein and Relativity rather than Newton. Actually, seeing Spin is involved, maybe it' Pauli and Dirac! :D

Oh and Correct Ball Paths would be a much better name/description. The British pair Cochrane & Stobbs stated these paths in their 1968 book 'In Search of the Perfect Swing'! It was the Yanks that got it wrong, but sold their way better (as they do)!
