There is no way I would pick a par 3 at Merion as a weak candidate. The set works beautifully. For me, the weak aspect of the course are the two par 5s, but if I had to pick one, it would be #4. I detest the water/bunker combo fronting the green and other than the marooned bunkers all over the course (maybe more of a maintenance issue?), this was the only architectural aspect of the course I questioned.
Stuart, thanks for the thread. Only Merion is strong enough to rise above the inane thread wars waged in her name.
Ciao
