Bob:
No doubt as one drops in the lower echelon in a top 20 you can have several different courses vying for the last few spot. Your point on Riverton is a good one -- fine Ross course and I've always liked a number of holes there -- most especially the 12th.
Keep in mind, when you say moving up or down courses I simply grouped courses in packs of five. So yes, it's possible that Laurel Creek could go one to join the rear end of the 2nd five and that Little Mill goes down one and is in the top portion of the 3rd five.
Candidly, I really liked Laurel Creek when it first opened -- one of the better AP designs -- but the proliferation of the housing has somewhat tempered my original enthusiam.
In regards to Stone Harbor -- I like a number of things there. The par-4 2nd is a superb hole with the H20 down the right. Clearly, much of the attention turned to what Muirhead did with a number of the other holes -- the renowned Jaws hole which since has been dramatically modified and the hole preceding it the 6th with its split fairway concept. I acually enjoy the closing hole there -- tough driving hole and demands a precise approach.
If you get up to the LBI area near the Jersey Shore try and play Sea Oaks. Quite good and also very reasonable on the $$ side of things.

Glad to hear you've got thick leather interior !
Be curious to know how many of my listing you have played? I agree that a final couple of spots can easily include one or two others and have the same number be bumped from what I listed.
Your original point is a good one -- once you move away from the Jersey Shore the overall depth of quality "must play" layouts diminishes. South Central and South West Jersey are not great places to find many worthy layouts although there are a few exceptions as I noted.
