I have found the setup no more difficult than gripping the club, checking my grip pressure and then bringing my arms in close enough to my body that my elbows are in front of me connected to my rib cage without any tension. This is the way I establish my radius to the ball the same way every time. My ball position is then adjusted to the club and shot that I am trying to play. This cue will help you setup consistently every time.
Remember that the distance to the ball changes with every club based on it’s length, but the distance from the club never changes based on the relationship of your arms to your body.
Need a drill. Practice hitting shots with a small towel or glove under your lead arm to establish this feel.
