He certainly designed a pretty devilish one at the 13th at Pac Dunes.
I suppose you could have a pretty decent conversation defining a macro v. micro undulation at the front of the green, but there are a number of holes at Pac where a ball that comes up short can roll off a good ways, including:
1st - more severe on the left side
3rd - more of a micro-undulation, but with the speed of balls running to the back of the green the shot becomes that much more precise
6th - Always be long on a front right pin
8th - pretty severe to a front pin from the left side of the fairway
9th (Upper) - balls seem to want to find their way off the front right corner
13th - anything that balloons is in danger of hitting the green and rolling well back
15th - with the wrong bounce balls from the right side of the green try to find their way off the front left
16th - a ping pong hole for many
Add in having to play many of these shots into the wind to firm greens. When they're a bit dialed in, shots well onto a number of these holes have the potential to roll back at you from quite a ways onto the green.
