Tom,
I think the answer would be: Somewhere in between.
My home course Tavistock CC(Haddonfield,NJ) is a Findlay design. After learning a bit about him, and some of his other designs, I would say that Tavistock is one of his best courses. Findlay's green designs at Tavistock are the highlight of our course. Next year as part of our restoration plan, we will be expanding the greens back to their original sizes. Jim Nagle who works with Ron Forse is our lead architect in the project. Perhaps he can shed some more info as to Findlay's work. I know that he is particularly fond of the green designs at Tavistock, and excited about the prospect of their expansion. When completed, I think we will have some of the most interesting and fun greens in this area.
From what I have found out about Findlay, it seems in his early years he was somewhat of a "Johnny Appleseed" when it came to designing courses around the Northeast. He did a fair amount of just rudimentary 9 & 18 hole courses that were nothing special architecturally speaking. As he progressed in the business, and became more familiar with some of the other Golden Age architects work, it seems his designs reflected his growing experience, and the influence of his contemporaries.
