SPDB:
In answering you question I would offer this:
Pine Barrens follows the philosophy of "Less equals more." I commend Eric Bergstol in taking the bull by the horns and getting into the design business because he really cares and loves the game (however, you should see Eric's new course called Branton Woods in Hopewell Junction, NY / just south of Poukeepsie -- I played it last fall in its early infancy and it has a bit more complexity in the demands it presents to golfers throughout the 18 holes).
The issue with Pine Barrens is that sometimes the philosophy of "less equals more" can be "less equals less." The course is layed out without all the irregularly shaped nonsense you see at too many courses. The holes flow nicely, but until you get to the 14th hole it's just a series of one hole blending so closely into the next that you fail to have the blood stirred.
From the 14th hole on Pine Barrens comes alive. The holes are still "minimal," but possess a clear punch and the blood is indeed stirred. When you finish the 13th hole and turn the corner to the long par-3 14th your eyes will open big time!
Mike Cirba is quite correct about the long par-5 15th hole for its distinctive character and the 17th is an absolute tiger of a long par-4.
Royce Brook (West) follows the philosophy of Steve Smyers and that means from the courses of his that I have played is about an architect putting his hand squarely on the final result. Smyers, to his credit as both an architect and fine golfer / he played for the Univ of Florida team w Andy Bean and Gary Koch, understands what bunkers can be in the overall presentation of a golf course. Bunkers should not be cat traps that allow you to hit Texas wedges out of them. That NEVER happens in a Smyers bunker.
The issue with RB West is something you articulated -- how much is too much. I believe bunkers should have some generalized purpose -- the course is public and for the average player the sheer amount of sand can only add to the total length of time on the course.
I like the strategic elements that Smyers uses / he always makes you use the old noodle before pulling the trigger and there are plenty of holes at RB West where you must be very secure in your ability to carry bunkers. When the wind is blowing through this flat and boorish piece of property you will have to control your golf ball throughout the round.
If I had to sound with one course over the other it would be RB West by a narrow margin. Can either of the two crack the state's top five public courses? My answer would be doubtful given the quality of the competition and in the case of Smyers I believe a better effort with his work at Blue Heron Pines / East. In that particular course the use of his bunkering is much more strategic rather than overkill.
Hope this helps ...
