I get what you’re saying, but Pro’s almost run just one tyre. The fastest their sponsor makes.
Scott-SRAM on the Aspen, TFR on the XR1, Thomus on the Thunder Burt (or Ralph).
It takes quite a lot of skill to comfortably run those tyres, especially on the front, and most of us are desperately searching for where we land on the spectrum of speed/skill.
