I have had alot of people tell me this about there One. It seems to be that if u mess around with the coverstock trying to polish it back up u lose some of the balls natual forgiveness that the ball has from the OTB coverstock. In our proshop we have shined some up for a cuple people after it dulled a little and they had a similar problem. I believe the "kit" you get from ebonite will work decently but I would NOT suggest you to polish it or dull it ever. Try to have then sand it 1000 aberlon pad side-to-side then a mixture of renew-it/hook-it/ and liquid sandpaper then sand it 4000, then put a litle hook it on useing the ball spiner, should give u a little more backend, but dont expect the same as OTB.
