Looks like the drill i suggested is working pretty well for you, or at least a close drilling. It does surprise me that 1k worked so well, i thought it burn on anything but a flood interesting find on the surface. I have mine shined on top of the factory surface it rolls more like a Bite now than anything else. Not as much backend but pretty good overall so a very versatile ball it is, this ball can be used on alot of shots.
