For what it is worth, my daughter's coach is Brian Smith at Longwood, who is very well respected on this board and many of the elite girls in the area get coached by him. This topic came up at a lesson recently, he believes the short game is more important. He believes is should be 60/40 or 70/30 practice time, I can't remember which, but a significantly higher percentage of practice time dedicated to short game. That of course doesn't mean you don't practice getting of the tee, but you dedicate more to short game.
Every coach I have ever talked to shares that thought process (I am positive there are some that don't). I have heard several coaches ask my daughter something along the lines of "in a round of golf which clubs do you use more, your driver or your wedges/putter" of course she answers "wedges/putter", then they say "so which clubs do you think you need to be better at?"
Now to really get myself in trouble......there is a reason you .....drive for show, putt for dough! FORE!
