Without stirring the "opening up private golf courses" discussion, I have to admit I have played almost none of the private courses in Seattle, so I can't make a comparison to Seattle CC, Aldarra, Sahalee, etc. I am strictly, not by choice, a public and resort player. So, compared to Chambers Bay, I would take Chambers. Compared to WA Na, I would take Rope Rider. A wash with Trophy Lake and the Home Course.
The one thing about RR is that it doesn't look dramatic, it is straight forward and simple looking, but scoring is difficult for some reason. I have played Chambers twice and shot 78 and 79; I have not broken 80 at RR in 12 rounds. The greens are deceptively hard to putt, and they have not fully matured yet. If I had to make a general comment, the hazards on the course are used effectively, despite their limited numbers. You won't find big, long bunkers extending to areas of the course you are never going to hit to. More likely, there is one a 250 yard carry off a tee box, not a series of three. If the hole doglegs, then you better move the ball left or right, because if you hit it straight with a driver you are in trouble. So the course lulls you into making bad decisions becuase it looks like you can't make a mistake, but when you do, it is severe. The bunkers tend to be fairly deep, so hitting greens from fairway bunkers is difficult because you must use too lofted a club to get it to the green.
Of the handful of friends and family members that have played with me, they all enjoyed it. It will be interesting to see how it changes with the softening and maturing of the greens.
