Review overview

Cleanup hitters and those with natural power benefited most from the CF9 Insane's design. It's perfect for players who can handle the end-load without sacrificing barrel control. Contact hitters should choose the balanced CF9.

The 2017 DeMarini CF9 Insane brought end-loaded power to the fastpitch CF line with the same composite technology that dominated baseball. This two-piece design gave power hitters the mass they needed for maximum distance.

Models Overview

The CF9 Insane featured Paraflex Composite optimized for fastpitch with strategic end-loading. The D-Fusion 2.0 Handle reduced vibration while the loaded barrel delivered the pop stronger hitters demanded.

Construction & Technology

Like previous years, the CF9 Insane is an endloaded, two piece composite fastpitch bat. The D-Fusion 2.0 handle has a stiff transition, built for the stronger player with top end bat speed. In the CF fastpitch lineup, the bat is the heaviest loaded bat. It is a drop 9. (The drop, you will recall, is the numerical difference between the length of the bat in inches and the weight of the bat in ounces). DeMarini claims the new composite (they call it paraflex) ย is "22% stronger" than in previous years. We would have no way to confirm this claim, but also no reason to doubt it. Considering the balance point on this CF9 Insane didn't change from the CF8 Insane, we don't see much value in an upgraded composite. From our research, we did not see any complaints on durability so, again, not sure if the 22% improvement in durability in the composite will be noticeable in the 2017 version.

Comparable Bats

Inside the DeMarini line, the CF8 Insane is a near match to the 2017 CF9. If we were shopping for the bat, we'd price check the CF8 for sure. End loaded two piece composite bats in the faspitch bats aren't particularly plentiful. However, the Drop 9 XENO Plus from Slugger is likely the most obvious competitor to the CF9. It is a big hitting bat built for the big elite hitter. (Check out our review on the Louisville Slugger XENO Plus).
