I've played Whisper Rock and thought it was very solid, tremendous greens with massive chipping areas. There were a few gimmicks but its one of my favorite courses in Phoenix. I've been waiting for his second course, I believe he was neck and neck with RTJ Jr. on Chambers Bay before losing out.
Whisper Rock was built with Gary Stephenson who was on Phils payroll. I'm not sure if he was involved in this new course?
