Scrambling percentage through improving my short game was the next piece I intend to work on. But since the woods/tee game is killing me the most, so it's the current priority (and as JB said, it has been for a long time now).
i've been playing golf for 15 years, and the #1 thing beginners were told has always been to work on their short game. but within the past year or so i've seen a study quoted where they determined that most golfers throw away more strokes off the tee than any other part of their game. i think that conclusions also accounted for poor tee shots that, while playable, left the golfer with a low percentage chance of hitting the green. so i agree that you need to work on your tee game, but if a lack of up-and-downs is costing you 20 strokes, that's more strokes than the 12-16 strokes from tee shots are costing you. then again, being able to hit good drives is so much more fun than hitting good chips, amirite?!
