Why does our preference or desire for a certain ball type matter? Simply because I like a "flatter" or "bouncy" ball is irrelevant.

It's not irrelevant -- the ball must bounce within a certain range, after all -- and since it's our job to ensure the ball is in that range, we can make it at the high end or the low end of the range if we so choose.
