Easy to handle, hard to crimp.
Color: Red/Black, Size: 0AWG-25FT Each
This cable is easy to manage (bend, etc) because it has an aluminum core. But for that same reason it is harder to effectively crimp, even with a hydraulic crisper.

0 Gauge wire 25 feet red,/25 feet black.
Color: Red/Black, Size: 0AWG-25FT Each
It is as advertised, Copper Clad Aluminum (CCA) but will work for very short runs and jumpers instead of eating my solid copper lines.
