The theoretical "turning point" keeps moving back. Ross pegged it (figuratively and literally) at 200 yards, Jones at 250 yards, modern designers at the mathmatically convenient (for contractors) 800 feet/260 yards, and now, I have moved it out to 850 feet for championship/back tees.
I base this on recently seeing numerous players use the backslopes of bunkers I placed at about 265 yards just four years ago to rocket their tee shots even further, and just having placed what I thought was a "pinching bunker" (come to think of it, it vaguely was shaped like a lobster) at 275 yards, only to see construction workers easily fly it, off dirt tees and in boots.
I usually use four sets of tees (Owners hate setting that extra block for some reason) split about a mathmatically convenient for contractors 33 yards (100 feet)
My old mentor said there were only two situations where he didn't favor sharp doglegs - one was when there were a lot of trees, and the other was when there wasn't. When you consider that short players may not make the dogleg, you can see why. For any sharp dogleg, I will usually remove trees, and use a bunker instead to guard the corner, if need be, allowing the short players a way around.
