While the Mastermind has been out a while, you're not going to find many (if any) balls that hook more or handle oil better.
If you've had it for a while, I assume you have had an oil extraction done AND have had the surface refreshed. If not, you must start with that, because if that is the cause for its not handling the new oil amount, the same thing will happen to every other heavy oil ball.
If, however, you're expecting to hook the whole lane, then that is a different problem. Sometimes the oil pattern does not allow you to play the lane the way you want. You have to play the lane the way the lane wants to be played.
