Not much will help, you have to learn to play the ball straighter and tame down the backend.
You can play with the cover but I doubt you'll ever get it where you like. If you sand it, even to say 1500 to 2000, it will tame the backend down. However, it is likely you would still have to move deeper or learn to fluff it some. If you polished more, then you are just making it even more uncontrollable at the breakpoint.
