Today’s golf is not really different from when I learned to play in the early 1950’s. Today’s power hitters invariably hit a fade. They set up pretty much the way Ben Hogan did.
I heartily recommend his 5 lessons as the Bible .
Everything in that book was right. Grip, posture, etc. my second book would be Tom Watsons , getting up and down.
Sam Snead had a pamphlet about his swing that was enlightening also
everything else is a spin off.
I was a single digit for many years and now time has caught up with me.
But the point is those books covered me for my golf career.
If you get caught up in stuff, Rotellas book would be helpful
