It depends

I do recommend a shorter swing to a lot of students while practicing! Due to a lack of Rotation and lat shortness, when a player lifts their arms the spine can reverse, they can lose posture, shoulder plane can flatten , etc, etc . So learning how to stay connected and how to get power from the ground while rotating is good for everyone’s game in my opinion! Trying to get good at a swing that relies mostly on timing takes a lot of swings and for joints that aren’t aligned anyway causes a lot of wear and tear on the body !
