Base hardness changes the game, not just the surface
Almost every brand sells a surface and leaves it there. Artisan sells the same cloth over different base hardnesses, and that's the variable almost nobody considers: a SOFT base sinks slightly under the mouse, so contact increases at the end of the travel and braking becomes progressive. A hard base glides more and stops abruptly. Choosing hardness is choosing how you stop, which is half of aiming.
