Since the ball manufacturers are guilty of the worst "cheating" I have no compunction about posting old methods of cheating. Some of the old "stuff" is better than new.
More length, sand with the initial tracks with 400-600 grit
More, more length, follow up with 600-800 grit
More, more, more length, follow up with polish(no grit)
More, more, more, more length, use 600-800 grit, follow up with 800-1000, then 1200-200 grit with polish.
All with the tracks
More hook:
Sand against the initial track with 400-600 will give earlier hook.
Sand against the later tracks with 400-600 will give later hook if you have smoothed up the early tracks
Later tracks to be adjusted per earlier post for later or early hook.
