Our Playbook covers Ball Flight Laws, Swing Principles, & your Preferences which includes how all that fits into the simplified Golf 8.5 approach to learning how to swing efficiently. The 8.5 PlayBook is used during our workshops and webinars to cover the 4 things to do before the swing and only the 4.5 things to do in the swing. You will have a complete understanding of your own swing. Golf 8.5 is simple and de-clutters that 6-inch attic.
