BillR,
I consider Manor's current course only a rough approximation of Flynn's original plans. As TEPaul pointed out, only 9 of Flynn's holes were built (we still have a short, 9-hole course which Flynn designed; it is virtually unchanged). When they're compared to Flynn's hole drawings, it's apparent we're missing many of Flynn's intended strategies. Part of the reason is that some of Flynn's bunkers weren't built and part of the reason is that the course has been neglected for many years and subject to the usual afflictions of older courses - overplanting and overgrowth of trees, green and fairway shrinkage, etc. Fortunately, Flynn's routing and seven of his greens are still intact and the topography hasn't been altered since construction in 1926.
I would rather defer to Tom and Wayne to say how the plans stack up to Flynn's other work. After seeing the Manor plans for the first time last summer, I was impressed. Manor is certainly not in Shinnecock Hills' or Boca South's league but it is a design that incorporates classic features and makes excellent use of the sparse natural features on the back 9.
Sadly, the land for the front 9 was much more interesting and Flynn's plan took great advantage of the natural slopes and streams there. For several reasons, his plan was never built and what we have now is a set of holes built in four different eras starting with Collis in 1929 and ending with Chip MacDonald in 1998.
We've hired Arthur Hills to develop a master plan which will address all these problems and give us an 18-hole course which as much as possible follows Flynn's design ideas consistently through all 18 holes. Hills' team seems as enthusiastic as we are to create something that Flynn would recognize as his own.
