Clint Daley was the master of that. He had entire arsenals built around a single ball with different layouts and surfaces. I think there was a Rule GP2 arsenal that covered everything from floods (the GP2's typical use) all the way down to light oil. Different pin and MB placements, a dozen different surface preps. He did another set a year later with Robo Rules, again covering everything from heavy oil down to light oil.
When surface is 70% of ball reaction, you can do a lot with two of the same ball with different surfaces on each.
