Peter-
Yes, I do get the opportunity to play with members and host unaccompanied guests. I would say that almost all of them can get off the tee fairly easy. Once they get around the greens they definitely struggle. Any player that plays stone eagle for the first time will AT LEAST 32 putts. There are days when I'm out there, and have no clue where a putt is going. Being on the side of a mountain, and already having the Indio effect, it makes it very hard to judge the speed on putts. Holes that players tend to have difficulty on are 5, 8, 12, 13, 14, 15, and obviously 18. Whenever they have to carry a ravine it scares the crap out of them. It is such a visually intimidating golf course, that a 10 yard carry over a rock filled ravine scares a player more than a 10 yard carry over a fake pond like other courses out in the valley. I've been with a guy before that was probably a 5 handicap; he hit excellent drives and iron shots all day. Once he stepped onto those greens he 3 putted at least 12 of the holes. It's the 3 to 5 footers that make you extremely nervous, you don't know whether to play the grain into the putt, or to just hit it firm at the back of the cup. Aside from all that, I feel that it is one of the best member courses out in the valley, especially in the afternoon when no one is out there and you can just make up your own holes. Personal Favorite is 11 middle tee to 4 green if you can imagine that, you could putt your whole way there.
