In summary, I believe someone who has discovered his or her best stroke can help you discover your best stroke. Knowledge of technique learned by one person can give another an advantage in discovering what technique works best. But it is dangerous to make that person’s stroke or any stroke description into your standard for right and wrong. Self 1 easily gets enamored of formulas that tell it where the racket should be and when. It likes the feeling of control it gets from doing it by the book. But Self 2 likes the feeling of flow—of the whole stroke as one thing.
