I worked with Jimmy back in the day. Never once did I hear no bending of the elbow or was I told to sway. If anything he was the first teacher that told me how to use my right side and "trace" the outside rail (the plane line). Spring the shaft was what I heard. Still good today.

I don't remember the book advising a sway necessarily. I may have just picked that up watching his star pupil, Curtis Strange (I am recalling that right I think).
