try this before you plug and redrill the ball( it's also cheaper ):this ball is wetsanded 400 grit and plished from the factory. scuff off the polish that's on the ball and wetsand it 600, 800, 1,000, 2,000 , and finally finish it off with a 4,000 grit abralon pad. this will cause the ball to burn a little energy all the way down the lane and tone down the backend. you could also change the direction of the sanding. sanding against the track of the ball would cause the ball to move a little earlier and tone down the backend. both of these possible solutions will require some trial and error on your part. be patient and good luck.
