The reaction shape seems to vary a lot based on how you drill it and how you release a ball. However, since the pearl coverstock does have particle in it, it will be smoother and a little earlier than a standard pearl. I don't know the numbers on the drilling on mine (we used the dual angle layout technique), but the pin is about 1/2" right and barely above the ring finger, MB just barely right of the thumb. My PAP is roughly 5 1/4 over by 1/4" up. For me, this is a very hard rolling layout. The ball picks up a strong roll and just keeps driving, very continuous. It's great for playing the lanes a little more direct with higher speed on moderately oily conditions, or getting left and opening up the lanes on a dry condition, especially when the shot gets over/under or the backends are flying. In the span of about 6 weeks, it got me a 300 and a couple 260somethings (front 9, light 8-10 one time. The other time, strike, chop the bucket, and go off the sheet). I've since hit mine with 2000 abralon after the cover started getting a little broken in and it gives me about the same look as I had out of the box.
