Will,
You and the others are forgetting something.
It's easier to hit a big green with a 5/6 iron than it is to hit a narrow, well protected green with a 3-wood off of an awkward lie.
I'll bet anyone on parring 11 vs 16.
The approach into # 16 is to a huge green.
The margins are enormous, and the lie from the fairway, benign.
The challenge is primarily to be on the same tier, or one tier lower than the hole.
On # 11, it's a longer approach shot, uphill, over a deep barranca, to a narrow, steeply sloped green, with pure disaster right of the green, versus a huge catch bunker on # 16.
Both great holes, but, I'll make par at about a 10-1 clip at # 16 vs # 11.
By the way, holes # 1, 2, 3, 5, 10 and 17 are very challenging as well.
But, I find # 11 the most difficult of all of them.
It' harder to make par and it's easier to make 6+
