Gentlemen,
The difference is ... Adjusted Address vs. Impact Fix...If you set up Impact Fix you are setting the right forearm and clubshaft on-plane with each other...If you move the hands back to adjusted address or a MID-BODY LOCATION you will see a difference in the relationship of the clubshaft to the right forearm ... Try it , See it, Do it Again and Again!!!
Food for Thought.... Hittin' Machine Set-up...Impact Fix
Swingin' Machine Set-up ... Adjusted Address
