There are countless eclectic course threads here, but I could not find one for modern courses, allowing more than one hole per architect. Perhaps a bit easier to decide on, but still one I would be more interested in seeing.
Here's a shot at one: nine holes by Coore & Crenshaw, nine by me, but eighteen different courses. Feel free to substitute as you wish.
1 - 4 - Cuscowilla
2 - 5 - Talking Stick (North)
3 - 4 - Tara Iti
4 - 4 - The Loop (Black)
5 - 3 - Streamsong (Blue)
6 - 4 - Pacific Dunes
7 - 5 - Streamsong (Red)
8 - 4 - The Renaissance Club
9 - 4 - Trinity Forest
10- 5 - Rock Creek
11- 4 - Bandon Trails
12- 4 - Ballyneal
13- 3 - Barnbougle Dunes
14- 5 - Sand Hills
15- 4 - Friars Head
16- 3 - Cabot Cliffs
17- 4 - Dismal River
18- 5 - Kapalua (Plantation)
Most of these were nominated in the voting for this thread, though I had to throw out the consensus favorite from Barnbougle, Ballyneal and Bandon Trails to make it work as there were not many nominations for holes 11, 12 and 13.
This is par-74 with five par-5's and only three par-3's -- we did not have many par-3's nominated although I believe we have built some good ones between us. I just didn't try too hard to make it par 71 or 72.
