NAF:
Couple of quick points ...
The 3rd can be stretched to a max of about 210 yards. The left rear pin position will clearly demand a fine approach. Much more wind exists above the tree line and many players will have to pick the right club because the front left bunker will see plenty of action if they're not observant.
The 8th can play to a max of 220 yards and yes you are right about the front pin placement, however, there is also room now for a rear pin placement in the far back right. The green was partially extended and there is a new rear bunker to protect against bold plays that go too far. Gauging the fluctuating wind will also be a factor for the best players to consider. I would not automatically write 3 on anyone's card so fast.
I concede the 14th is a birdie hole but only with a well played approach. Given the fact that the 15th is probably the most demanding hole they will play I see no reason why there can't be a hole that yields birdies when played correctly.
The 17th as you described is a real treat and many golf fans unfamiliar with the hole will marvel at its design strengths. I really do believe that if the pin is placed far right the hole is tougher than when its back left. The landing area is very tight and the shot better not have too much pace or it won't stick to the putting surface.
Overall, the par-3's at the Black are not at the level of Winged Foot / West but in my mind better than what you find at Baltusrol / Lower. We shall see in June ...
