Hardy mentions one plane swings of Ernie Els(purest one planer), Michelle Wie, Ben Hogan Sam Snead, Chad Campbell, and Tiger(written before his swing changes).
Two plane swingers he cites are Tom Watson(purest two planer), David Toms, Davis Love, Karrie Webb, Nancy Lopez, and Hale Irwin.
Speaking of shoulders, that Manzella guy has a chip on his--maybe it's because he is David Toms' former golf coach. I have yet to hear any teaching pro hold up David Toms' swing as an example to follow--outside of this guy. And most teaching pros who were at the teaching summit liked Hardy's presentation.
