I think we all know that quarterbacks, kickers, specialists have certain preferences on footballs. They know a lot more about it than I do. They're a lot more sensitive to it than I am.
The way I've talked about my research process is that it was like magpies. I was just sort of moving through all these books and when something shiny would pop out I'd be like, Ooh, I love it! and I'd pluck it out. It's fun to figure out how to use those bits you really love - like I'd read about gold shoes with cork heels. Obviously, Margaret would have to wear those shoes.
