Tim,
Good subject.
# 14 at PV from the back tee is really, really, really hard because it's a pass/fail shot.
The other holes mentioned are challenging to difficult, but not "hard" in the sense that # 14 at PV is hard.
The consequences for not executing the tee shot are dire, whereas, on the other holes mentioned, failure to execute is marginally punished.
You may make bogey, or even double, but you won't be making triples, quads and higher, routinely, like you will at # 14.
