I recently felt a little lost with my swing. My club was crossing the line at the top, and I couldn't figure out why. I was looking at my backswing in my reflection on a clubhouse window, and Metro instructor Greg Thrall comes over, diagnoses the problem in under 30 seconds, and the next day I fire a 76, which ties my personal best at Metro.
To paraphrase the PGA Tour commercials, these guys (Metro instructors) are good. Think about taking a lesson.
