Well, My AMP was drilled label, w/pin like right above my ring, touching the top right corner of my fingerhole. This ball oob was particle pearl, came polished, this ball was great for me b/c it created area, swing it, it came back (on a THS), tug it, it held w/o snapping away. I'm guessing even though the drilling is relatively weak, the cover/core combo made it strong, it really didn't flip, but a strong arc. Now bear in mind, I only throw about 15 mph and put more revs than normal (speed deficient), so the weak drilling & cover allowed the ball to slide, while the particle and my revs would make it recover. The DA seems strong (3% particle), but it comes matte finish even though it's particle pearl? I would drill this label also, I just wanna know this ball will have some recovery on THS's and etc, and be predictable.
