i had my fury smoothed finer with a 4,000 grit abralon pad( it was at 2,000 ) and i noticed a seeable difference resulting in more length and more backend reaction. today i was able to play several lines all with good success. i threw several games with medium speed, 45 degrees of axis rotation, and swung the ball 14 to 7. then i threw several games from the outside line.....higher speed, 20 degrees of axis rotation straight down 6-7. finally, i threw several games from a deep inside line, slower ball speed, 60 degrees of axis rotation, swinging the ball from 25 to 11. thus far the octane coverstock and the torsion core are proving to be a good combination.
