Don and Sir Rick are both correct. I played Diamondback on Round 4 last year. I enjoyed the challenging layout and hospitality from the employees. However the rough was ridiculously long. We lost balls all day (including 1 of my own a foot into the rough) even when all 4 of us saw where each ball went. I also advise scouting the course so you can get familiar with the holes and the drives you’ll want to hit.
