I was never one to change the surface on my equipment. I always just left my equipment shiny. I just drilled a 505a and hit it with a 2000 then 4000 abralon pad and man what a difference. I can not believe how smooth this ball is. Still is as strong as any other 505a i have drilled but this one is not so skid flippy. Not sure how this would affect any other brand but taking the polish off these track balls makes a huge but better difference.
