Drilled 2 of them for myself when they came out.
One pin up 4.5" from PAP and factory polish over box finish.
the other pin down 4" from PAP with extra hole down and factory finish also.
Both ball roll extrememly well and make a nice strong arc to the pocket for medium to heavier volumes. The pin up ball reacts better later in the sets when the heads get a little burned up and there is a little carry down. Balls gets around the corner very well.
The pin down ball react great on the fresh heavier volumes. Nice and smooth reaction with no over jump and both have a very nice hit. A very good inexpensive ball for medium-medium heavy volumes.
We sold alot of them last year to people looking for a great value ball with top notch performance!
