I agree w/ Jonathan but will hedge and call PD & AS even. The only other RGD I've seen is the first course at Stonewall.
I would have guessed Jonathan might have gone w/ the New Zealand RGD courses.
By my eyes, Doak took more risks at AS in the design.
To me, the range is wider at AS - the holes that I enjoyed were really spectacular(e.g. 3, 4, 5, 6, 7, 9, 10, 12, 13, 15, 17). And the AS ones I didn't fully buy were lesser than anything at PD. And to be a Doak contrarian, I did think the AS Redan is in the bottom half of such efforts compared to the Raynor/Mac. versions I've played. #17 at AS is my favorite RGD par 3 so far.
I did stop for a hamburger at AS between rounds and that was a regrettable mistake.
