So far I have only thrown it for 5 games. Drilled it pin up 5 inches off axis. Mass bias at 45 degrees with a low hole. What I am seeing is a very clean motion through the front part of the lane, with a HUGE backend motion. Honestly this ball changes direction down lane the fastest than any other "A" ball Track has made since the numbering system. I thought the 718A got around the corner great, this ball does circles around that. Going to be a great compliment to our lineup so far this year. In terms of hook for me which means the earliest rolling to the latest. 919C, 716C, 300T, 811A, 503C. Going to throw it more this weekend to see some different conditions.
