Simon -
Am pleased to hear you had such a nice round. Is your SH contact a (former) Scot? There's a couple there.
Notes about the course:
1. They definitely do not overseed the greens, and I don't believe they have been doing the fairways either. A couple of the very first years they did overseed, but it turned out that the traffic didn't require it. So you actually saw the course at its (relative) scruffiest, with the bermuda not yet completely recovered. Btw, the current greenskeeper (Tom Werner) used to be at Colonial, and has gotten rave reviews from the members.
2. Did you manage to hit the speed slot on #3? Hitting a draw just inside that fw bunker on the right will give you a really nice bounce forward.
3. You didn't quite have it Monday, but that second shot on #6 is designed to be into the prevailing (SE) wind. So if the water behind makes you chicken out, you can have a very long putt on a fairly tricky green. Some TX pros (Crenshaw, Kite, Brooks, Leonard) were out for an event and one of them 4-putted that green.
4. Number 10 is a mean hole. Mean.
5. I hope you had a front flag on #11, the medium-long par 3. It would have been playing with the wind kinda quartering from back right, and you definitely could have landed it short to bounce it on.
6. I haven't been out there since the hurricane. There were two really important trees on the course - in the corner of the dogleg on 16, and then the one on 18. Don't know how bad they got beat up in the storm.
