Especially when you see comments on this site such as "toe in the face to negate the fade tendency of hitting"....whats that about?
Also, in several books about Hogan, especially Jody Vasquez's book....
Observers of Hogan note that he setup with his club face about 5-10 degrees open at address. Hogan found that worked for him. I wouldn't worry about how much someone toes it in at address or not, I'd worry about how square it is at impact.
