I've been striking the ball much better the last few times at Metro because of one swing thought: balance. I find if I set up to the ball with good balance, then swing thinking only about staying balanced all the way to the follow through, everything just sort of falls into line. I know, this is not a new or radical thought. But it's working. I wanted to learn a little more about balance, so I did a search on this blog's golf-specific search engine and turned up a few good articles for you.
