Yeah it's balanced but swings a slight heavier then a TZ.
The PowerArch made the TechWrap possible. Before the PowerArch the DeMarini patent kept this bat on the drawing board. So, yes the TechWrap has the PowerArch.
I've swung a 27oz OGTZ and a 27oz black TechWrap side by side, and the TW was both more endloaded and heavier on a scale.
you are sneaky, going around the patent
