There's been more questions and more debate on the Right Forearm. I thought this David Orr YouTube video would help explain quite a bit.
Furthermore, here's a Web site link explaining 'The Magic of the Right Arm.' (http://www.golfswing.com.au/ppage.php?id=164)
This is pretty much the Brian Gay golf swing. He happens to be a master of using the Right Forearm in his golf swing. And from the looks of it, once you start to 'get it', it's very easy and repeatable stuff that will produce great shots.
