Might sound crazy, dumb, or just absurd, but what about taking 6 or 7 of the same balls. Drill each ball with a different pin to pap distance. like the first one put the pin of your pap, then the next one and inch out then 2 and so on and so forth. but don't add any weight holes (for like 2 or 3 shots each) to change the reaction of the ball. then add them half way through to give possible lay-out recommendations. just a thought, but might sound crazy as you would be using 6 to 7 of the same ball.
