Practice my man. Everything inside 60 yards will either make or break your game. If you can develop just a slightly above average short game to go with those long straight drives, you will be looking at low 80's in no time. I don't even touch my driver. I just don't have control of it. I hit a really good 3 wood off the tee, so that makes up for it, but I would love to be able to hit my driver.
Anybody have any hole in ones? Last summer, I holed one on a par 5 from 170 or so out for eagle. In all honesty, it was the luckiest shot ever. It was a completely blind shot. The green is out the bottom of a cliff, so I was actually using a 9 iron from that far away. I've also stuck em with in a couple of inches before on par 3's, and even hit the flag once, but yet to get a hole in one.
FWIW, I was mid to upper 80s at the beginning of last summer, and then everything clicked and by the end of July I was constantly in the low 80s and even high 70s a few times.
