It will be a 100% composite bat with an improved composite weave that should make it stronger and provide more trampoline effect from the barrel.
Pics and more info to come as soon as DeMarini gives us permission to release them.
[Updated March 29th]
The best upgrade on the new Demarini CF5 is the lighter and stronger composite weave. This means a larger sweetspot and more trampoline from the barrel. Demarini didn’t stop at the barrel, the new end cap is also a leap in technology that uses an odd looking array of triangles to help lessen vibration on the new CF5 bats by focusing that energy back into the barrel (check out our pics below).
The 2012 Demarini CF5 bats should be available the third or fourth week of April, 2011. (All the new CF5 bats come with Free 2nd Day Air shipping from CheapBats.com)
The grip of the new CF5 bats has changed to a gold color and it looks like it has triangles pressed into it.
