Tom MacWood;
From my experience with Ross courses, I'd say that the stereotype is generally true in this case. On the other hand, it's also true of Alex Findlay, as well, so I think it was probably a fairly common design technique.
But, I agree about the tendency to over-stereotype Ross on other matters, such as his grass-faced, flat bottomed bunkering, which your recent thread completely dispelled.
For instance, Ross himself didn't like uphill par threes, yet his Mark Twain course in New York State has four of them!
