Scott:
And by the definition you gave, Huntercombe really has TEN holes with centerline hazards? I would think that at some point, short of that, the idea would start to get repetitive.
[Which reminds me that at May River Club, Mr. Nicklaus came back in for his last construction visit and decided to insert bunkers such as you describe into six different fairways ... all of them right in the landing area, mostly just left of center.]
Centerline bunkers are hard to combine with scruffy edges, but Pacific Dunes does have something of the type at holes 2, 3, 6, 12, 15, and 18. The last three are par fives where the centerline hazard comes into play on the second shot.
