Frans, how are you going to change path and not HSP, while keeping AofA desirable? What I am getting at is CAUSE of path. There are three major influences on Club Path (concerning TMan) VSP, HSP, AofA. I'm guessing you dont want AofA any less or negative, VSP is already on the vertical side, only other variable is HSP. Voila.
Cause and Effect. For example if someone said, she needs to fix her high hands through impact, well thats great, and I agree, but why are they high? Thats what needs fixin.
As for face, as I've said before, I think it will change with a more positive HSP, matter of fact, it may end up being too open. Remember, according to the data on page 1, her face is open to the path and the HSP. I am not a believer that the golf swing works like plug and chug, change the HSP and face remains the same. Matter of fact, if she changes HSP, not only am I guessing the face will change, so will AofA (more positive) and VSP (less vertical).
The goal is not to make 5 changes to see one improved result, its to make one change to open up for many improvements.
