So there is a difference that you can feel at low speeds and, perhaps, during an emergency. I choose common sense over the "If I don't feel it then it doesn't exist" option. It may ride good, it may feel good and it may kill you when you least expect it. (But that's motorcycling in a nutshell, isn't it?) You can cheat on ATGATT, tires and maintenance and get away with it -but why chance it for a few $ if you don't absolutely have to? What if you're wrong and someone dies because of your advise? When you watch that video is your brain hiding in your wallet? It's obvious there are much better options for a safer tire, personal riding impressions aside. There, I'm off my soap box.
