Watch the MX16 in action here
The Track Mx line of bowling balls are designed with the medium rev bowlers in mind. This type of bowler needs a ball with moderate overall strength. The Mx16 takes a medium strength MR-8 Hybrid cover and combines it with the strong i-Core to create a ball that will handle some oil but help through the transitions for bowlers with medium rev rates.
