Anyway thats the theory. With a bit of practice anyone can do it.Its just daunting aiming for a spot well of the pitch!
It still won't work if you bowl too fast though. Conventional swing is caused by smooth flow on one side of the ball and a turbulent boundary layer on the other. Bowl too fast and both sides go turbulent. Having one side shiny makes it easier to keep the flow smooth, so that's why shining the ball helps.
Sounds an intereresting technique to try, though. I bowl inswing, but that's because I discovered a few years ago my natural action does that, so I'm not "trying" to do anything in particular.
