I have my LevRg currently at 2000 abralon, ball is drilled pin left of ring, and slightly above (lefty drilled). MB is just left of, and below the thumb. This ball still likes to roll early, but at 2000 it does save some more energy and hit better in the pocket on a THS. I was having some issues with it rolling up early at 1000 (factory), but I wanted it to still be earlier than my Momentum, and it is a great compliment to that piece. Good luck. I am going to take it down to 500 for the Shark also, but the cover on this ball adjusts very easily, as does most MoRich bowling equipment.
