The 2014 CAT 5-Squared is an uber hot bat that is one of the best ever made. It is illegal in the 33 and 34 inch models but the 32-inch BBCOR version is fire. We love it.
Models Overview
To be sure, the bat is not for everyone. But it has a balanced swing and feels terrible on mishits. That said, it can hit the living crap out of the ball if you square it up well enough. It consistently records some of the hottest BBCOR speeds we can generate. It's a fantastic bat.
Construction & Technology
The CAT 5 has the sting dampening in the knob. Other that it is a single piece alloy bat with a smaller barrel.
Performance Comparison
The CAT 5 was the first version of the CAT 5. They followed that up with a CAT 5-Squared which was promptly made illegal in the 33 and 34 inch versions.
