[John Graham]

Exactly what point is that? Can I hit a High straight or a Low straight shot?

The point of that is with a solid strike, as I understand it, with the impact plane(chord of the circle pointing at the target) and the straight low plane line(tangent of the circle) being parallel to the target but right of it, a straight shot is not going to happen ever.

If you have the requisite skills, low shots and high shots can be straight for sure.
