Since all golfers have individual anatomies and skills, no one swing pattern is going to work for everyone. I prefer to eliminate the “tipping point flaw” that leads to several other flaws and reduce swing thoughts to a minimum…hopefully one.
The setup, takeaway and transition have to match. Anything that happens after that, including impact, is a result of a the aforementioned three things and how well they match.
Eliminate excess movement, while not limiting free movement.
