I have the same ball and I use to have problems like you are experiencing.Everyone have given you good advice. You also need to learn finger position, lane condition. This ball is very agressive and hook on the backend. one of my favorite finger postion is, spreading my pinky and fore finger. Spreading both will even out the reaction. I am not saying this will work for you , like it work for me but give it a try. I have over 100 games on this ball. In Dec I shot my highest with this ball 279. I hope this will work for you.
