The Relationship between Ball Position and Club Faces
You may ask that why clubface or the Titleist 917 Driver Australia itself? Yes, but we need to talk to the detail point of one thing to another. This variation is sometimes used because, though the ball typically follows the angle of the Titleist 917 Fairway Wood Australia's face more than it follows the direction of the swing path it doesn't follow the face absolutely and completely. So learning the feel of how much to open the face on any given shot requires some trial and error and, therefore, may take a while to learn - particularly given all the possible variables.
But it is not uncommon to open the stance 45 degrees, or more, again depending on the purpose. But extremely open stances are usually only used in extreme circumstances. Now, on opening the stance by moving the left foot behind before hitting the Titleist AP1 Irons Australia, if one sees at the golfer from a line perpendicular to the line from ball to target the ball will still look reasonably in the middle of the stance. However, at line perpendicular to the open stance line, the ball will look closer to the right foot, i.e. back in the stance.
So if your swing path matches your open alignment then yes, the ball position would be farther back, from the line perpendicular to the open stance line that you referred to above, even though if you looked at it from perpendicular to the target line it would not appear to be back in the stance. Would this ball position be called "back," then? I guess it depends on who you ask, but if you are thinking about it in relation to the swing path then yes, that ball position would be back.
In addition, you need to pay attention to your stance or posture especially the open stances when hitting the ball using clubfaces. If you can coordinate the relationship between the three above, it would be more easier for you to swing a good shot.
