Wayne,
I've been thinking about the preference that some have for NGLA over SH.
I think some of it can be attributed to fairway width, the sense that the margins of error are greater, hence the golfer feels more comfortable on the tee, AND with greater margins of error, errant shots don't come to rest in such difficult positions.
In addition, I think the INTEREST at the green and green surrounds is far greater at NGLA because those structures are more dramatic.
Are there more unique greens in golf than the 1st, 3rd and 6th ?
The green complexes are so unusual, so sporty, that their appeal is almost universal. Look at # 7, # 8, # 10, # 11, # 12, # 13, # 15, # 16 and # 18. Look at the features near the green, like # 17, # 16, # 1, # 2, # 3, # 4, # 6, # 7, etc., etc..
I think the greens and green complexes at SH are more natural, but, the greens and green complexes at NGLA are more FUN. Fun to approach, fun to recover to and fun to putt. And, that I think is the principle distinction.
NGLA is perceived as MORE FUN.
