That's probably the case. What's the difference in the ball motion if any on the house shot vs the Shark? If you can find out the layout on that ball and tell us that might be helpful. Ask your pro shop guy if necessary. It should have been drilled according to your PAP because I'm sure this is not your first ball, in which case the markings in relation to the fingers don't tell me much. However if it was not drilled to your PAP you can tell us where the markings are or take a pic.
