The DeMarini Voodoo Black bat is made of aluminum alloy.

'A composite impedance function'

In my oppinion it would be the COMbat or a CF3 Black.

Black Hills State University's 2014 25th-75th percentile ACT Composite Scores are 18-23, meaning 25% of students scored 18 or lower on the ACT Composite Score, and 75% of students scored 23 or lower (i.e. 25% of students scored 23 or higher).

NO! Black Angus can ONLY be ALL black in order to be deemed purebred. Also, an animal that is deemed to be Black Angus MUST have DNA tests done on the animal, the sire and the dam to prove that it is indeed purebred and not a composite. The animal you are talking about is a composite breed, which is a result from crossing Hereford with Angus, or even crossing Angus with a Hereford-Angus F1 cross.
