Tom -
I'm holding the course to very high standards indeed, unfairly high; those Par 4s on any other course would be standouts. But that said, and relatively (or better, 'relationally') speaking: for me, standing on the tees, the architecture / the design / the 'concept-thought behind the design' took the centre stage on the Par 4s in a way that it didn't on the Par 3s.
I don't think I'm parsing out the 'architecture' from the 'golf hole', but I may be doing just that; all I can say is that it felt like, time and time again on the Par 4s, I 'saw' the architecture popping out from the total picture in a way that I didn't see with the Par 3s. With the Par 3s (and the 8th hole), the features, the playability, the challenge, the choices, the aesthetics and the 'concept-thought behind the design' all blended together seamlessly to my eyes; they were 'one' -- and there was no 'architecture' there.
There was a simplicity about the Par 3s that was very appealing, a kind of humbleness of idea & execution that engaged me very much and that felt like 'golf'. A poor widow quietly (and secretly) dropping two dollars into a Red Cross donation basket and a young billionaire announcing his $1 million on facebook and having a building named after him -- both are acts of 'charity', but the former is the heart of it while the latter is a display copy.
This may all be 'wrong', Tom, and one day I may be adding my mea cupla to this thread; but for what it's worth: these thoughts/feelings are not the product of years of reflection, but what I thought/felt literally moments after driving away from the course after my one play -- and I was semi-embarrassed by them even then.
I remember talking just a couple of days days later to Joe Hancock, who asked me what I thought of the course. I told him that besides the 8th I liked the Par 3s best. There was a pause, and then Joe said 'Ah, that's interesting. I don't think I've heard that from anyone before' -- and I thought 'Ah, geez, I must be an idiot, and Joe's just trying to be kind and say it nicely!"

PS - I remember as well not having the honesty or the heart to tell *you* the same thing a few days later, knowing of your love of the place and given the difference in the value of our opinions
