Russ made suggestions and approved them from what I heard. He may have been more involved than that, but I can only tell you what I do know. In the case of Chatham Manor, I do know Russ gave a basic formula to Carl McAllister, who nailed the blend in two tries. In the case of the others, I believe Carl made the matches mostly on his own. I taste tested three of the Matches before they were released, though CM was not one of them.
