Thanks for your contribution, bray, but respectfully, I must disagree.
You can "Paint with the Right Side" as desribed by the NBC analyst Johnny Miller, and still be Swinging. In fact, you must feel this.
Despite the Passive Right Elbow Accumulator (#1), the Swinger delivers -- via his Pivot and Left Wrist Throw -- a stiff-wristed Right Forearm Slap (Pitch Major Basic Stroke / 10-3-B). The Right Forearm's Basic Stroke (7-3) and the first joint of the Right Forefinger, Loaded with its Lag Pressure, Traces the Straight Plane Line and accurately Delivers the Clubhead to the Ball (1-L #1 through #10). All while Extensor Action (6-B-3-0-1), Right Triceps Pressure via the heel of the Right Hand against the Left Hand Thumb, creates maximum Power Package Structure.
Bottom Line: Even in a Swinging Stroke, the Right Side is always active.
Ask any professional tennis player what his most powerful ground stroke is and he will tell you the, "FOREHAND" (versus backhand). The forehand is powered by the right side.
