I do like #11 at Essex but would not be my top mid-range one shotter even in the same county. I prefer #16 at Myopia for the runaway green and drama of not knowing where your ball landed but watching for the roll-out. One can legitimately hit the golf shop with the teeshot, which adds a bit to the mix as well. #16 is also the last of the truly precise approaches one must hit at Myopia, and thus a likely match decider.
Traveling farther afield, I'd prefer:
#7 at Cypress
#6 at Pinehurst No. 4
#4 at NGLA (Redan copy)
#8 at Mammoth Dunes
#5 at Pebble
Of them all I'd have to put #7 at Cypress as the finest mid-range in the US. It's perhaps among a very small handful of transitional threepars, where you've emerged from the forest and enter the dunes all in one glorious 175 yard stretch.
Thank you for this thread - a nice reminder of how lucky I've been to travel to these places.
