Curious about swing ??

Hello Friends,
 I see bowlers not getting the right swing at their bowl. Why !! The answer's here....

1. For even a conventional swing, the ball must be 70% worn and teared and one side should be shiny enough.
2. The rough or worn side should be on the side where you want the ball to swing. Say, you want out swing so the worn side should be out (off side of the batsman)
3. The pace should be enough and requires a high bowling action.
4. You cannot swing the bowl in a short pitch or area.
5. Common, now swing it off.
