Wow, what are the odds. I see that this is an old post, but I was trying this very thing at the range today, based on a tip I saw on TGC. But the Pro giving it was only suggesting it so that you could feel correct lean at impact. Well, I'm just back from a long absence and was really struggling with my approach (7-9) irons, so I figured, what the heck. Worked like a CHARM, I tell you. Not a huge lean, mind you, just enough to bring the grip to the "right side of my left hip," or just left of your belt buckle. I was making cleaner contact immediately, and I'm actually considering this for a tournament tomorrow. Might not be a long term answer, but there is no arguing the result, it made a huge difference in contact and ball flight. YUGE!!
