With its Rough Buff finish, the C•(System) v4.5 will offer a lower friction factor with similar response time to friction alternative to the C•(System) 3.5. The new C•(System) v4.5 is best used on medium to oily lane conditions when you need to use a breakpoint further down the lane with a quick response motion to increase pin carry.

Type
Pearl Reactive

CFT v4.5 is the next progression in Chemical Friction Technology. The CFT v4.5 coverstock has a lower friction factor than CFT 3.5 which improves length through the heads and mid-lane without sacrificing the quick response and improved traction on the back-end.

I-Block Symmetric Core

The new I - Block Symmetric core was created by modifying the original asymmetric I – Block core (which has a symmetric base and an asymmetric flip block) to have an asymmetric base. By creating an asymmetric base with an asymmetric flip block on perpendicular axes the two asymmetries cancel each other out making the core shape symmetric. The core shape was also thinned and stretched to increase the RG min while maintaining the overall differential.
