The two best short par 4's I've had the privelage to play quite a few times are the 2nd at Austin Golf Club and the 17th at Crystal Downs. Niether one fits your criteria, but none the less they are tremendous golf holes. I will never forget the first time I set up the 17th at Crystal Downs and was like, "Man this seems like a long par 3!" I absolutely love that golf hole, I've played it so many times and I've never even came close to having the same shot into the green, I'm still convinced that the original tee box is now where the cart path is, but what do I know. As for Austin Golf Clubs #2, I'm biased as I play it as much as possible, and its always a challenge, usually more mentally then anything, I love to see guys take a cut at it with the wind with them, it tips out at 287 so everyone thinks they can get there, good luck, if you get it there, it isn't staying there! The green is a tiny devilish creature that seems to have more breaks in it then I ever read.
