You make it sound like CCA is inferior to OFC. Aside from the point that it carries 50A less, the performance is still there and it's not any worse than OFC. If the OP is running under 3k he can run CCA without any issues. Running OFC under 3k is just a waste of moneyI would just get the Kolossus Flex. You will never worry about your wire. Ever. Something might not be right, so you can immediately say that the wire has nothing to do with it.
