Unfortunately a US Open set up is not really condusive to the architecture shining through. Holes I would look to--
#6, if a tee shot finds the rough, the pond likely will come into play and the golfer will have a difficult choice to make.
#7, this hole's architecture will benefit from a little moisture, still firm and fast, but not so firm and fast that the hole's interesting aspects become a farce.
#10, for whatever reason I love this hole and I like the way the USGA has treated the back of the green. The approach will require great thought; the highlight may be the number of interesting recovery shots around the green.
#11, a very unusual par-3, the way the green sits above the tee, in the wind it is super intimindating, God help the man who misses the green right of the bunkers on the right...unfortunately I have personal experience...there is hell of a lot of architecture down there.
#14, a beautifully natural hole
#17, another great par-3, requiring great thought and controll.
Those three par-3's in particular stand out to me...they prove that length is not a requirement in creating an interesting and testing golf hole.
