I played here yesterday. Early Sunday tee time and went out with 3 locals who used to play Maryville all the time and all seemed quite pleased with the new track.
I was charmed. Holes maintain their same corridors, but there were many bunkers added and they are serious hazards. A good bit of earth moved too so that a course which was once flat as a pancake now has at least some movement on holes in ways the leads to greens being slightly elevated, some options as to being in a high spot in the fairway or a low spot which is partially blind, etc. I thought there were several good holes; the best on a first glance being #13, which is very similar to Riviera #10 as a short par 4 where the thin angled green between bunkers means that playing out to the left is probably the best option. Green doesn't compare to Riviera, but it has some nice character to it, including a back half that runs away and makes pitches to back hole locations very tricky.
More than anything, I was just pleased to see the course busy, seemingly mostly with locals and probably 80% of people I saw walking on a brisk Phoenix morning that turned to a warm afternoon.
Looking forward to meeting up with folks there next month and hearing Mr. Fought discuss his work.
