The Swinger's Motion is On Line whereas the Hitter's Thrust is Cross-Line (7-23). Hence, the (Cross-Line) Angle of Approach procedure is not compatible with Swinging.
Thanks for the reply Yoda
But, confusingly, the 10-5-E Closed Plane Line can be worked into the Swinger's procedure, e.g. to hit a draw.

When you say "cover", you mean visually cover (i.e. from the player's view) don't you? I ask because the plane cannot be so upright that it's vertical to the ground!
