I realize this is a VERY old thread but my instructor was working on my posture and frame today and referenced Donnie Burns. I Googled it and this thread came up. A lot of what's in here is terrific, so thanks for that.
However, I'm still looking for the interview or class he was talking about. I guess Mr. Burns replied (when someone said it doesn't feel natural to stand that way) something like " Well then don't do it! But realize there are those of us who have worked for thousands of hours to make if feel natural!" I hope to find the actual interview or quote.
