For what it's worth, when I was designing the Quarry at Giant's Ridge, I took the owner's rep to Tobacco Road as well as Fazio's World Woods course to give them an idea of what the Quarry could look like. They had been hesitant, but agreed to go with the TR/WW look, providing it leaned more to the Fazio and less to the Strantz in difficulty. Not sure I got there, but there is a design influence, given he had no protégés' to carry on his work.
The discussion about great artist who didn't care about difficulty has me thinking about the legacy of Robert Von Hagge, who had a different style, but similar priorities.
