I will second a few of Rob's noms ...
#2 at Talking Stick North for a par 5. Featured in Doak's Anatomy of the GC. Hugely wide fairway but with OB hard left and the green up against it, sooner or later you're going to have to take it on.
#12 at TS North. Again the OB is hard left. Now you also have a dry wash right of the green. Challenge the green (and the OB very close to the left of it) and you can either drive the green or, at minimum, leave a simple chip up the length of the green. Drive safely out to the right and you're left with a wedge or short iron in that must clear the wash but not go long into the OB. An excellent hole built around angles, an obvious but less severe non-hazard (the wash), and a less obvious but very severe hazard (the OB). No bunkers on this hole, as well.
I also am a big fan of #13 at WeKoPa, which he mentioned as well.
However, I don't like #15 at WeKoPa. The idea is there but I don't think the hole plays well. It's so much downhill that even when the course is firm I've never seen anyone who plays a shot short and right ever actually get a kick onto the green.
