Pros:
The course is indeed of excellent quality, as several have mentioned. Great big tee pads, beautiful signs, and several great hole placements, #1 and #17 coming particularly to mind.
It's long and difficult, and usually pretty fair. It's a course that certainly you should have played if you live in Austin.
Cons:
However, I do think this just isn't quite the level of a few other courses in Austin like East Metro, Circle C, or Bible Ridge.
As others have mentioned, the holes are extremely repetitive, particularly on the back nine. Look at the hole lengths - with one exception, all the par 3s are between 325 and 405, and all the par 4s are between 720 and 849.
Pretty much every hole that comes to mind on this course is on the front nine. It feels like more work went into that. I mean, hole #1 is a championship level hole on every level. It's gorgeous. #4 is great. #7 with its dual fairways is fantastic.
But the back nine is just a slog through the woods and gets a bit unfair. The particular problem I have is the number of holes with early chokepoints, which are basically just accuracy tests without adding any strategic interest to the course. And 18 is just obviously an "OK, we got to the picturesque hole, now we need to head back to the parking lot" hole.
And this isn't their fault but the total lack of elevation change really hurts the course. It very much plays into the lack of variety.
That's a loooooong way to say this is a great course with a few flaws that keep it from being the best in Austin.
