Black Creek is a completely different animal from every other Silva course I have played, largely b/c he built it conciously to emulate Raynor's style rather than in his own.
Most of Silva's work is in New England; most of it is for mid- to low-end clients, although a lot of the recent stuff is moving in the CCFAD direction. There are a lot of Silva courses (especially older Cornish and Silva courses) that are nothing more than average publics. On the public side, the two I have played that are head-and-shoulders above average are Waverly Oaks and Red Tail. Waverly Oaks, in Plymouth, MA, is probably the better test because of the wind, but I prefer Red Tail, on the old Fort Devens military base (now closed) in central Mass. The front nine is particularly strong, especially the really neat short par 4 8th. The style is also fairly typical of Silva. I'd say it's a 5 on the Doak scale.
