Steve Boccieri, founder and guru of Boccieri Golf, has an excellent pre-swing balance tip that caught my eye.
Boccieri knows more than a little about weight distribution. His claim to fame was the development of the heavy putter and the subsequent multiple variations of it. He's also the king of the Secret Grip, a weighted grip for putters and clubs, which I've used with some solid success.
