Typically . But guys like Luke teach Hitting with Horizontal . Go figure. The compensation being a deeper right elbow . The advantage being better compression no leakage. Per 2-C whatever drawing.
Similarly Hogan swung with Angled , sometimes, not always , didnt always swing left , hold it off. I mean every good golfer can manipulate the face right? The ball response is physics only.
One major difficulty with horizontal hinging and hitting.
Rotating pressure point #1 . Because the thrust is on plane, the rotation at point of appplication is disruptive for me.
