Correct me if I'm wrong, but I get the impression you've carried your 10 handicap for as long as you've been tinkering with your swing? Now I'm certainly not suggesting that we as golfers shouldn't try to better our game, but isn't the point really to lower your scoring average? You've got enough clubhead speed to break 80 from the tips at most golf courses. Do you want to be better at golf, or just make your swing prettier? Maybe if you sharpen your short game and putting the rest of the game will get a little easier. Maybe you won't stress on those approaches and drives as much when you know you can get it up and down from all over.
They are short books, but I quite enjoyed "Raymond Floyd, The Elements of Scoring: A Master's Guide to the Art of Scoring Your Best When You're Not Playing Your Best" and "Tom Watson's Strategic Golf". I think they are worthwhile reads, especially for the player who is just starting to think about course management and how to determine the "smart play". Plus "Strategic Golf" has lots of pictures. I like books with pictures.
Thanks, johnnymarlboro! Yeah, I've been stuck at the 10-handicap plateau for a while. But before that I was a 16-handicap. And tinkering with my swing has made it much more effective and brought it down to a 10........
