Ok fellas, heres my opinion and please dont think I am correct here. But if you take an Abralon Pad say 4K and do a ball by hand, you get a true 4K look. On the other hand, when u place it on a ball spinner, the lines overlap themselves causing the grit to be much higher than the actual 4K it was intended to be(making it look much more shiney).
With bowling ball technology in todays time, you can actually take every ball to 4K and pretty much bowl on anything. Given the type of ball along with the right layout, one doesnt need polish. So he is right to an extent... There comes a time, Im sure that when there isnt much head oil, but is the answer Polish??? Thats something u must ask yourself and then it becomes a trial and error situation. I think the true answer would be no, because when the heads are fried, polished stuff is not going to burn up and produce an undesired hook... With the statement I just made only applies to a person using a ball spinner though so please keep that in mind. I feel like placing the ball on a spinner and using 4K is like really using 6-8K Abralon when one does it by hand or in a resurface machine.
Dont think I dont have any balls polished because I do. I just feel like in the back of my mind, there isnt a need for it. Sometimes on a demanding condition, polish can make for a tough ball reaction... Just my 2 cents. John Davis
