Interesting somewhat related side note: when I was younger, I was one of the first people through the doors of the Titleist Performance Institute in Carlsbad. I went once every two months for a few days of observed practice and occasional experimentation. One of the experiments was to hit putts with noise-canceling headphones on (the type that make it so you can't here anything). Surprisingly neither I, nor anyone else they had through the door (world class pros included), was able to tell what type of a ball we were using while putting (the A/B was a super soft Tour Balata and a super hard "distance whatever"). Take the headphones off and we could tell with near 100% accuracy. What we thought was "feel" was really audio feedback.
