Looks like the good old pin st 1:30 little bit of side weight. This is a generic drilling used when the PAP is unknown. I disagree with the rest about the early rolling bit. The cg is in the center of the grip, not providing thumb weight for early roll. The mass bias (6-3/4" on a straight line from pin through cg for symmetrical) is on the left side of the thumb hole, possibly in the track, providing an arcing motion. For early roll, the mass bias would be right of the thumb. If the ball does happen to roll early, it is because of the cover, not the drill on this one.
