You're probably right. Whatever's your worst aspect of the game is probably the most important to practice (but don't neglect your other game either) since that is where you will add the most strokes to your game. I guess I should have said at least for me the short game is the most important. I played with a couple of older gentlemen the other day who could putt somewhat decent, but the rest of their game was horrid. If they could correct that they might be able to break 100.
