You're incorrect. Distance is dictated by the club head speed and position of the ball on the club face. Great form creates leverage which increases swing speed and that makes the ball go further. In 2000 Tiger wasn't the biggest player on the tour yet he was one of the longest hitters. Why? Because he was clocked swinging his club at 130mph at one tournament.
uh, spark, other than what u said position ON club face, i think u made the exact point i did, i.e. skinny tiger ball go far. i guess i should have noted a heel, toe, high on face or low on face will impact distance but figured most knew that. thanks though!
