Shot mine in a PBA pattern tourney this past weekend (which I won, btw). I threw it on the Shark (203), and the Scorpion (247). I had it at 2000 abralon (no polish) and it read both patterns very well, and the carry was excellent. I could play the track area on the Scorpion, and played inside 15 on the Shark, both with good results. Ball is pin next to ring, mb next to thumb. I hope this info helps, good luck!
