Steve:
Just my personal opinion but at LuLu you should be very careful about what you reproduce in the vein of things like mounds. You should not forget how early your course is in Ross's career and try to very much stay in character with the look of that very early time in his career!
I looked long and hard at that mounding behind #13! It's not ordinary Ross at all, it's very rudimentary, extremely old fashioned and you should treat that for what it is--an architectural feature of real interest of an early time and era.
There're probably plenty of other areas and features of LuLu that should be treated the same way. That's much of the interest and heritage of your course and I sure hope the members, committees, Ron, whomever, understand that fact. Things like that could be LuLu's true asset.
What you should do is track some of Ross's other courses of that era and study some of their features. Massachusetts maybe a place to look. Check with Dave Miller or Ed Baker of Charles River or maybe Essex or Salem or some of the really early Ross courses. Maybe get Ron to get in touch with Brad Klein, Gil, Ron Prichard or Brian Silva.
The evolution of Ross's career and the alterations of his style of architecture is a whole separate study, in my opinion. Even my course with some of its square greens with the corner "flare-outs" are really interesting, and I'm so glad they're now being restored.
PS:
On #15, I think you have a very interesting decision to make--basically some really interesting evolutionary buildup vs original bunkering and green restoration. I'd prefer you stick with the evolution but I don't think you could go wrong either way, except for with today's game there's no question in my mind that the evolution is the best for today's game with that hole! As it is it's such a good green-end and front bunker situation!
