I agree with NicholasE. You would be in pretty good shape with those 2 balls. However, they are both pretty strong balls. I would look into getting something that can handle the lanes with less oil. Either of the Avalanches would work well. I do believe the UZ will be more versitle than the BP. The enmotion coverstock is made for length. Therefore, since the ball come rough buff OOB, it will start a little sooner. HOwever, you could throw some polish or something on it to lengthen it and strengthen the backends. So if it were me, I would probably do the Ultra Zone and Avalanche Pearl.
