I drilled my 930T with the pin below the ring finger. Cg was kicked 2-3 inches and a good size hole was placed along the midline. The reaction I got was very poor on alot of conditions... One that stands out is a THS. I tried just about all surfaces you can think of, and even polished it at 2K Abralon, and it still didnt want to work good on the THS compared to some of the other choices.
After trying multiple surfaces, I then took it back down to I think 400 with the Brown Lane Masters Pad. It now works better than ever when I see 45+ ft. conditions. 85% of the long conditions I hit, I can take on with my pin down 920A but for those 15% that wont, I simply bring this bad boy out. If I had to rate this ball I would give it a 9, just because 70% of bowlers may not use this ball for what its intended for. Just dont force this thing to work on what its not meant for and you will be fine. John
