Question: what is the difference between the demarini insane and zen?
Answer: The CF Insane, not be confused with the 2019 CF Zen, is a two piece composite fastpitch bat with a more endloaded swing weight. Granted, it does not swing as heavy as a bat like the Slugger PXT, but it does swing about 10% heavier than the CF Zen. The Zen is the Insane's lightweight and more popular cousin.
