I have 3 of them drilled. The one thing for me I found was to take the factory finish polish off with 2000 abralon and the re-polish it with factory finish. The factory uses high pressure machines to polish the balls and the polish gets real hard and your reaction can be inconsistant.
My PAP is 5" over and 1/4" up. Rev Rate 375, 45° axis rotation, 17° axis tilt. ball speed off my hand approx. 18.5 mph
Ball# 1: Drilled with a 5 1/2" pin to PAP, Drill Angle is 60°, VAL Angle is 70°. The pin is below the middle finger and the surface is curretly at 2000 Abralon. Ball reads the mids very well and makes a very strong defined move to the pocket. I use this ball a lot to start out with.
Ball # 2: Drilled with a 5 " pin to PAP, Drill Angle is 60°, VAL Angle is 40°. The pin is above the ring finger and the surface is curretly at 2000 Abralon with factory finish polish. This ball is very good when the lanes open up and I can get in and wheel it.
Ball # 3 Drilled with a 6 1/2" pin to PAP, Drill Angle is 75°, VAL Angle is 45°. The pin is above and left of the middle finger and the surface is curretly at 2000 Abralon with extender polish. This ball is good when the lanes are getting torched. It is very clean through the fronts and makes a some what snappy but controlled move at the back of the lane.
