Asking Industry Insiders: Road Tire Width. Fatter is Faster?

There's a hot topic these days about road bike tire width. Everyone seems to be coming out and saying wider is faster. I thought I'd walk around the show floor of the Taipei bike show and find some industry insiders and ask what they think is the fastest setup.
My interviewees were a little skewed towards Asian brands / riders because most of the western brands send their marketing people over here, and I wanted to try get more info from product guys / racers.

P.S: I recorded the outro before talking to @gplama I'm not calling him slow. Hahha.
