Having a low-handicap vs a high-handicap has nothing to do with understanding golf and course architecture, or providing intelligent golf course "reviews"; nothing at all. In fact, it's often more important to get input from golfers who play like the majority - that is, not down the middle of the fairway then onto the greens most of the time.
This subject reminds me of one of my favourites stories, too. Alister Mackenzie's playing a match at Leeds, about 1926. He mentions to his opponent that he's heading down to Australia to design some courses. Mackenzie plays terrible, gets killed by this guy in their match. Afterward, the victor asks Mackenzie, "Did you say you're going to Australia to design courses?" The Good Doctor answers, "Yes." The victor adds, "If I can give you some advice, don't let the Australians see you play golf."
We all know the results of Mackenzie's Australia trip - Royal Melbourne, Kingston Heath, et al.
