Typically though, I'd say golfers need to work on the face.
When I was on Trackman last year, I would occasionally hit some hooks and over-draws. I thought the path was too far out to the right, but the reality was that my path was pretty much square like it was the entire session, but the clubface was more closed on those hooks and over draws.
It really made me appreciate the value of clubface control because my face would be about 3* closed instead of more square and that simple, seemingly minute 3* completely changed the shot for the worse.
If we are talking push hook I think path less to the right so I want to feel over the top almost.
Duck hook I gotta fix the face first and see what happens to the ball flight. If I am push hooking it and open the face that could turn into a push-push cut.
Honestly though your question is very vague. I have a buddy who is a decent player, 5 handicap, and he hits push hooks all day long but will occasional miss with a over hook or straight hook. I would not touch his face because he tends to cross the line at the top with a very "wide arcing" backswing and then get under it so the path goes to the right. I have helped him with some drills to swing more left, especially with the irons. We set up a preshot waggle like Graham McDowell to feel a leftward move. Never once have I said open up the face, other then to tell him if he hits mr snappy duck hook that "dont believe anyone who told you that you came over the top".
