Why The Oval Ball Flies Straight
When positioned vertically,the oval ball is almost impossible to hook or slice because it has two axes of spin. Slicing your club across the face of the ball has no effect because the sideways spin that results is immediately counteracted by the ball’s simultaneous tumbling spin. As seen below, each half revolution the ball makes as it tumbles through the air, reverses the direction of the sideways spin that causes a round golf ball to curve.
Why It Can Fly Round Corners
The GolfCross® ball will curve in a pre–set direction because once it has been set spinning on a particular axis it maintains its angle of orientation in space in the same way as a spinning gyroscope or frisbee. If the ball’s angle of rotation is leaning over to one side then it will curve round to that side.
The Tee Cup
Because the flight of the ball is controlled by the way you position it, a rubber tee cup has been developed to hold the ball at any number of different angles when teeing off. If local rules permit, it may also be used on the fairway. The cup may be used on its own or stretched over a regular tee after pushing the tee’s sharp end through the bottom of the cup.
Basic ball positions
How the oval ball flies through the air is determined not so much by how you hit it but by how you position it before you hit it. Once you’ve learnt the five basic positions common sense will tell you how best to position the ball in various playing situations.
