I can't think of a full swing vertical hinger off the top of my head.

But it is a centered motion that produces no sidespin. The ball will simply change trajectories, unlike with an angled hinge where there will be a slice spin imparted on the ball.

For a "stinger" shot, I'd say the hinge depends on Hitter/Swinger. For a Hitter, I'd probably hood the face a bit (or use a 2-iron, for that matter) and use an angled hinge. For a Swinger, dual horizontal hinge.
