I have drilled 3 cells in the last 3 months. 1 for me with the TJ Layout and polished. One for my brother, pin under ring. and one for my teammate, pin over ring and polished. so far to date my brother shot his first 300 on the lastnite of league and just last week went 299, 802. My teammate has 3 299 and 1 300 and on the last nite of league i went 300, 290. 232 822 so thanks roto for a great ball with a cover that is very user friendly.
