Anthony - 7 is a cape style dogleg and I would probably consider #16 a dogleg as well, although you really have to play from the back tees to feel it turn.
Sean - I just got back from Pinehurst and had a great first experience on #2. I really like the way you explain these "hooks". I found that with the crowned greens, it is the "hooks" that give you the line of play. On holes # 2 and 3, he hooks the holes around bunkers which force you left with ariel because of the carries. But on # 5 and 10, the hook allows you play along the ground.
Remember like it says on the 1st tee... He is trying to get you to solve "a variety of problems that will test every type of shot". So there should be a way use the slope of the greens / approaches to get your ball closer to the hole: Left side of green on # 2 and 3, run to the middle. Short right on #5 kicks you to the middle... 12, 13, 14, 16 and 18 do the same in their own way.
