Tom Doak,
In the rounds my son and I played over three days at Streamsong, not once did we ever feel that the greens were too fast.
We also never felt that any hole location was improper.
My general feeling is that if the hole is cut in the green, it's a reasonable location, taking slope into consideration.
As you know, I think the 5th hole is one of the great holes in all of golf.
Challenging to difficult hole locations make it even better.
To a great degree I think that medal play and the requirement to post a score has served to eliminate great hole locations from daily play, hole locations which challenge the golfer on their approach and recovery as well as with putting.
The dicier the better, for me.
When I play NGLA, I love the hole locations on # 1 in the old back bowl or on top of the spine, anywhere near the perimeter on # 2, on the upper right tier near the edge on # 3, back left on # 4, anywhere dicey on # 6, 7 and 8 and near the back perimeters on 9. Front on # 10, left upper tier on # 11, behind the spine on 12, behind the bunker or close to the perimeter on # 13, ditto 14, back upper tiers on 15, right perimeter on # 17 and back, back on # 18.
Those hole locations heighten the challenge and the fun.
Is there a better combination in golf ?
