Alright, I will be the only one dumb enough to try this. The following is a composite layout that would work logistically, and would offer holes of the most comparable style.
Front 9
Bandon #3 Par 4 (Play as Par 4 from lower tees, obviously the bunkering is a disconnect)
Bandon #4 Par 4
Bandon #5 Par 4 (The most "Pacific like" hole on Bandon)
Pacific #11 Par 3 (Yes it would be a 200 yard walk from 5th green)
Pacific #12 Par 5 (Nobody complains about this walk)
Pacific #13 Par 4
Pacific #14 Par 3
Pacific #15 Par 5
Pacific #16 Par 4
Par 36
How would that front 9 compare with County Down's front side?!!
Back 9
Pacific #17 Par 3
Pacific #18 Par 5
Pacific #1 Par 4
Pacific #2 Par 4
Pacific #3 Par 5
Pacific #4 Par 4 (Last of ocean drama, ultimate par 4)
Pacific #5 Par 3 (Demanding par 3)
Pacific #6 Par 4 (Take a chance if you need a stroke)
Pacific #7 Par 4 (Strong par 4 to finish)
Par 36
This excludes Pacific 8, 9, and 10. So the obvious question is, are Bandon's 3, 4, & 5 better than Pacific's 8, 9, & 10? It is difficult to compare Bandon's #3 vs. Pacific's #8, and Bandon's #5 vs. Pacific's #10 as they are different pars. I would say that by losing Pacific 8,9, and 10, you gain two world class holes in Bandon 4 & 5. In my opinion those holes would add to the fun, memorability, and shot values of the "Composite" course. Not to mention perhaps the finest front 9 on the planet. Yes there would be a disconnect, especially in bunker style, and cohesiveness is lost. But individually, you would have 18 great holes. Ideally a composite course blends holes of the same style to choose the 18 best.
I guess the fun thing would be to imagine, what if that land had not already been used and Tom had the above land available to use for Pacific Dunes. Bandon would definately have suffered greatly. I think the resort is far better off as the two courses are both extremely strong EXACTLY AS THEY ARE.
But if I owned the place, and had it to myself, perhaps these would be the 18 holes I would play.
