It's funny how the bulk of the thoughts on QH are from 2009 and the course has undergone many changes since then. I will clarify my remarks by stating I've attended the Tour event numerous times since 2006, was there when Tiger won in 2007 and saw Rory hole the putt on 18 to shoot 62 and claim his first PGA Tour win in 2010. I played the course prior to the 2016 Wells Fargo which was just before the most recent of course renovations prior to the 2017 PGA Championship. I attended the PGA and I've had the good fortune to play the course since those changes.
I will say QH is one of, if not the finest conditioned course in North Carolina. Keith Wood and his team do a phenomenal job of producing excellent conditions on a regular basis. One of my favorite things about QH is that it has a short Par 4 on each side (8 and 14). This produces scoring opportunities but with risk and challenge present. And, I do think moving 16 green over close to the lake was a good thing. But from the perspective of a golfer and golf fan that enjoys this tournament more than any other non-majors, I liked the course much better overall about ten years ago. I liked the downhill par 3 second hole that no longer exists, and I liked the old par 5 fifth hole much better than the two holes that replaced it (par 3 4th and par 4 5th).
Also, this may come as a surprise considering I am a superintendent, but the course used to have many more trees than currently and I enjoyed the overall look and feel of the property then than now. I always thought QH was a southern version of a classic northeastern course. It's still great, those are my thoughts.
