Back to the topic, long drivers of the ball tend to have a slow transition which sets one up to produce lag. Lag cannot happen with a quick transition.
If more amateurs would slow down their swing tempo, they would gain yards and find themselves in the fairway more often.
One additional thing, keeping one's head still while pivoting around a stable spine/core, produces balance and effortless power.
This concept is so simple yet so many players search for all complexities thus missing the point.
I am a swing the handle proponent and one cannot do that with a fast swing.
